FMS 3.0 stops accepting connections after 1-3 days, restart required

Hi,
We have a custom application that is running on FMS. Server is dedicated just for fms, there is only one application running on the server, with more instances, average traffic is 3-15 simultaneous users. The problem is, server suddenly stops accepting connections (after 1-3 days from restart), from this point it is impossible to connect to any instance, and fms server must be restarted. When the server crashes, the admin console can see all open instances, can close instances, can restart fms. There is nothing logged, that would explain this sudden failure.
Second problem is, cores are connected and disconnected too often, causing client to reconnect (takes 2-5 seconds).
Do you have any idea what is causing these problems?

We have seen similar issues and the best work around is to have your clients connect on alternate cores/servers. The way to accomplish this really depends on your type of application.

Make server stop accepting connections for some condition

I have a server accepting connections from clients. We don't know in advance how many clients to accept so the server just keeps accepting connections in an infinite loop:
for( int i = 0; ; ++i)
server.accept();What needs to happen is some condition has occurred and the server should stop accepting connections. i.e.
for( int i = 0; stop_accepting_connections == false; ++i)
server.accept();
System.out.println( "No longer accepting connection.");Essentially some external event (actually the first accepted client thread) will set stop_accepting_connections to true and break the loop.
Problem is even when I break out of the loop clients are still accepted. I'm thinking this is caused by server.accept() being a blocking call and even though we've jumped out of the loop the last server.accept() call is still blocking and listening for a single client. I've tried 2 clients connecting when we've broken out of the loop and only the 1st one is accepted, the second just waits.
1. Is there any way to really stop listening when the condition is set (i.e. how to kill the last blocking accept())? I don't want 1 last trailing client.
2. For the rejected clients, how do I stop it from just waiting i.e. print some error msg and let it end?

Problem is even when I break out of the loop clients are still accepted. I'm thinking this is caused by server.accept() being a blocking call and even though we've jumped out of the loop the last server.accept() call is still blocking and listening for a single client.No, it's caused by the TCP 'backlog' queue, which pre-accepts connections even before you call accept().
1. Is there any way to really stop listening when the condition is set (i.e. how to kill the last blocking accept())?Close the ServerSocket. The thread blocked in accept() will get a SocketException: socket closed, which you should trap and proceed acordingly on. At this point you probably just want to exit the accept() thread.
2. For the rejected clients, how do I stop it from just waiting i.e. print some error msg and let it end?See above. Any clients which are in the backlog queue will get some kind of SocketException or IOException, probably 'connection reset'.

Why do my Aironet 1042s stop accepting clients after a month or so?

Hello, everyone.
I have a test setup with a vWLC (7.5.102.0) and four APs. Two Aironet 1602i APs were purchased for the test and have been functioning for months with no issues.
Our other two APs in this setup are older Aironet 1042Ns. Before the vWLC test, the 1042s had been operating in standalone mode. I converted them to LAPs manually following the procedures at http://www.skytale.net/blog/archives/37-Manually-converting-a-Cisco-AP-to-LAP-mode.html. The conversions were successful. However, after 1-2 months of uptime, the 1042s will stop accepting most or all clients until I reset the AP. Then they're fine again for a month or two. (They don't both stop at the same time; each AP suffers the issue separately, generally weeks apart from the other one.)
The clients can see the SSIDs, but get errors when they try to join the networks. This applies to both new clients and ones that had previously associated.
The 1042s list boot version 12.4.23.3, IOS version 15.2(4)JA1$, and Mini IOS version 7.5.1.73. Each one is located in a different building, if that helps.
The 1602s list boot version 15.2.2.0, IOS version 15.2(4)JA1$, and Mini IOS version 7.4.1.37.
The syslogs on the vWLC aren't showing anything about association or authentication failures, so I'm puzzled. I'm not sure where to look next. Anyone seen this before?

Hi,
Yes, along with this you need to upgrade the firmware of AP 1042s and then check this issue.

Flash media server stops accepting connection.

We have one application in which we are using flash media server 2.0.5. We dont know why it's stop taking connection occasionally at that time we can't enter into the managment console. We get a white screen. When we try to enter user name and password it's does not accpet the credentials. We are not getting anything in the log.
Port number 1935 and 1111 of the particular system where FMS has placed are working fine.
Does anybody have any idea why we are facing this problem?

That's a pretty old version, have you thought of upgrading?
There are a few reasons this could be happening. You could be reaching the limit for connections or bandwidth.
There could be a problem in your server side coding that is stalling the app.
There could be a problem with the service itself and it's maxing out on memory or CPU. I don't know why you are getting a white screen for anything, the management console has never been white for me and I suspect that it's more of a local computer problem unless it's the same computer you are running the service on..
Any more information on the license, server hardware or environment?

Issue on Cisco Unity Connection after performing 'utils ntp restart'

Hello everybody.
There's a client with Cisco Unity Connection 8.5.1.10000-206. After doing a 'utils ntp restart', the following message showed up:
Communication is not functioning correctly between the servers in the Cisco Unity Connection cluster. To review server status for the cluster, go to the Tools > Cluster Management page of Cisco Unity Connection Serviceability.
The client states that there was no service for 5 minutes and wants to know if performing this task shoud be disruptive or not and if there is any official document from Cisco stating this.
See SrvConnUnity_1.jpg sent by the client after performing the ntp restart.
Right now the service is normal (see SrvConnUnity_2.jpg attached). The client also sent a 'utils ntp
status':
admin:utils ntp status

Hello Patricio,
On the command line guide you won't see any downtime requirements for the Unity Connection server:
Command Line Interface Reference Guide for Cisco Unified Communications Solutions Release 8.5(1)
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cli_ref/8_5_1/cli_ref_851.html
Utils ntp restart
This command restarts the NTP service.
Command syntax
utils ntp restart
Parameters
None
Requirements
Command privilege level: 0
Allowed during upgrade: Yes
Also on the caveats i do not see any particular mention for this: (Caveats could be found applicable to CUC)
Release Notes for Cisco Unified Communications Manager Release 8.5(1)
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/8_5_1/cucm-rel_notes-851.html
Breaking up the output of the "utils ntp status" there are are two considerations:
admin:utils ntp status
ntpd (pid 10899) is running...
     remote           refid      st t when poll reach   delay   offset jitter
==============================================================================

First, you are using the ip address 127.127.1.0 which is the referenced used for the local system clock, the asterisc means is the preferred option as there is no other IP available. This is not a good practice and not recommended.
Secondly the stratum is unreliable, meaning too high to reach or too low to be accepted by Unity Connection.
If you would happen to run 'utils diagnose test' you would have probably seen an output as the following example below:
admin:utils diagnose test
Log file: platform/log/diag1.log

And on the RTMT (Real Time Monitoring Tool) you would have seen a Critical event:
Condition:
The best external NTP server, , is stratum , which is unacceptably high. External NTP servers must be <= strata 8 and should be <= strata 5. NTP server strata can be verified using the CLI 'utils ntp status' command ('st' column). Try using different NTP servers.
Problem cause:
All specified external NTP server(s) have unacceptably high stratum values. Network issues exist or the designated servers have unreliable stratum values.
Information is self explanatory and therefore reassures the need of having a NTP different from the server itself.
By the snippet you sent we can know that it is the publisher server, as the Subscriber polls this information from the Publisher.
Installing the Operating System and Cisco Unity Connection 8.x
http://www.cisco.com/en/US/docs/voice_ip_comm/connection/8x/installation/guide/8xcucig020.html
"Cisco recommends that you use an external NTP server to ensure accurate system time on the publisher server. Ensure the external NTP server is stratum 9 or higher (meaning stratums 1-9). The subscriber server will get its time from the publisher server"
Documentation also reaffirms the need for that NTP to be accessible otherwise your system can be degraded. Some addtional information which would be interesting to know is:
- Why did they had to restart the NTP in the first place?
System Requirements for Cisco Unity Connection Release 8.x
http://www.cisco.com/en/US/docs/voice_ip_comm/connection/8x/requirements/8xcucsysreqs.html
"A network time protocol (NTP) server must be accessible to the Connection server"
On the Cisco Unity Connection Serviceability> Tools> CLuster Management screen shot you sent i see that the ports were "Not Available" and that the customer stated "there was no service for 5 minutes".
By no service did they mean that over the phone they heard a disconnected tone or a failsafe message?
Additionaly after the servers resolved from SBR the Subscriber never recovered entirely as it did not start the Conversation Manager service.
Bottom line if they are able to reproduce it then it would be worth a while checking with TAC

Listener Won't accept connections after time (OERR TNS lost contact)

I am running 8.1.7.0.1 on Linux 7.1 (all patches applied).
Things were going great until this morning and my listener now
seems to be flaking out. After I start it, people can connect to
the database but within a few minutes they start getting
ORA-12547 TNS lost contact when they try to connect. If I
tnsping the database from my client I get the "No Listener"
message. Doing a status on the listener shows that (2) service
handlers are active for my database...when I first start it there
is only one. What does that mean? Does anyone have any
suggestions? Thanks in advance...

How is your Apple TV connected to your Computer? I know that you are doing this wirelessly, but is their an access point being used between your computer and the Apple TV? If so, is it and Airport Extreme, or a third-party router? If third-party, what type? N? G?
What is the distance between your computer and the bedroom? What type of computer are you using Mac or PC? If PC, XP or Vista?
Sorry to ask all of these questions, but I'm trying to figure out if this is a problem with the distance and, if so, can the router be tweaked to increase its broadcast to your bedroom.
If the the distance is too great, you might have to purchase an Airport Express to work as an extender. On the other hand, if you are using a Linksys Router, you can change the Radio Beacon to improve signal. If you are using an access point google Beacon Interval, Fragmentation Threshold, and RTS Threshold.
For example, change your Beacon to 50, your Fragmentation Threshold to 2304 and your RTS Threshold to 2305. This will improve the quality of the signal. You do this by accessing your Router through your web browser: type 192.168.1.1 (or whatever is the equivalent for your router.)
Well, I'm walking between the raindrops here. Good luck.

RDP Services do not accept connection after cluster failover

Hi guys,
i am having weird behaviour on my Windows Server 2012 R2.
server 1
- 10.100.1.201
server 2 - 10.100.1.203
VIP - 10.100.1.202
when i perform remote desktop session to server 1 and server 2 after both servers are being rebooted, they are working perfectly fine. during the remote desktop session, i perform a cluster node failover switching node to server 2. immediately i perform
the task, my server 1 connection will hang and not able to login anymore.
strangely, when i am connection from the same server zone and perform remote desktop, they work perfectly fine and will not disconnect me from neither of the server 1 and 2.
i am suspecting the network routing mess up during the cluster failover, but from the route print, there are identical and has no problem with it.
any one here has the same problem i experience?
zhiyuan

Hi,
sorry if i lose you ... here is the story
node 1 - 10.100.1.201
node 2 - 10.100.1.203
vip - 10.100.1.202
when both server restarted, i can remote to both servers, no problem.
1. RDP to both node 1 and 2 together on their physical IP. Connected successfully.
2. checked the Active node on node 1. Perform fail over from node 1 to 2, node 1 RDP session loss connection immediately. checked on node 2, cluster node active on node 2. no errors.
3. perform node 2 to node 1 fail over. Node 2 RDP session loss connection immediately, node 1 session came back. checked cluster node active on node 1. no errors.
4. in order to have both can continue to rdp, perform restart on node 2 (the node cannot reconnect), after reboot, rdp back to normal.
5. firewall team confirm connection has reach server, server not responding to rdp apparently.

Computer stops accepting charge after standby/prolonged use

I have what appears to be odd, but relatively predictable problem with my white, late 07 macbook and a new 60 watt power adaptor. Usually the system works just fine, but occasionally if I plug it in after the computer has been on standby and used for a while, the computer doesn't recognize the adaptor is plugged in.
If I remove the battery and replace it with the adaptor plugged in, the connection immediately becomes active and the battery starts charging. This leads me to believe it is some type of software issue that can be resolved or reset. The guy at the apple store when I bought the adaptor said to hold down the power button for five seconds when the battery is out to reset something, but it didn't seem to do anything.
Any ideas?

What you were told to do was an SMC reset and it is important for the adapter to work. You will also want to update all your software. To perform the SMC reset pull out the battery and disconnect all cables. Hold the power button for five seconds. Then replace the battery plug the power back in and power the computer on.

I lose my internet connection after 5+ minutes-must restart to get it back

In the past day or two when I use the internet with my MacBook Pro-13" running Snow Leopard 10.6.4 I suddenly realize after 5-25 minutes that I am no longer connected to the internet. (I have 2 Internet Service Providers in my home-office setup)
This occurs when I am using either of the ISP's: VOO or BELGACOM; and it occurs if I am using via ethernet cable (primarily VOO) or WiFi (primarily BELGACOM). But it fails with wireless VOO and wired Belgacom, too.
Suddenly I see that my WeatherDock 2 is not updating or I check the weather somewhere else or I'm going to a new page in Safari and it just has a white page for a long time and I know the internet is GONE. Sometimes the NETWORK Preference panel still tells me I'm connected (wired LAN type); although generally when it is via wireless it turns to the red dot and tells me I am not connected.
With Wireless if I try to reconnect, often it brings up the WPA password box - but it never connects.
Logging-out and loggin-in does NOT work; neither does sleep and waking from sleep.
But if I do a restart- automatically my preferred WiFi server is working great - but for how long? Generally 10-20 minutes then gone...
HELP - this is a relatively recent problem (last few days) - and a nightmare - can't get anything done!
GLAD I SAVED THIS BECAUSE I CANNOT SEND IT - AFTER JUST 5 MNUTES THE NETWORK CONNECTION IS GONE AND I HAD TO RESTART-- Hopefully this gets sent.

Saturday 9 October 2010

Thanks and I shall be trying these things - plus perhaps a new router (I have 2 now, and will try to just use the newest one - eventually might get an 8 port out as I have 2-3 computers plus 2 printers...)
Since I have 2 different ISP's (VOO and BELGACOM) I make sure to turn-off the one (unplug or if WiFi just turn-off WiFi). The eMac does NOT have WiFi.
The Belgacom modem has its own built-in WiFi - again the eMac cannot access that - other than via the PBG4 accessing that WiFi and the eMac connected to the PBG4 via FireWire 400 cable for internet access. That works and doesn't seem to cut-out.
I'll follow your other hints-- no "MINI" involved - just an eMac 2005 without WiFi and a PBG4 and my MacBook Pro-13" mid 2010 (and that seems to have a HD problem...)
I'm not sure how to "RELEASE AND RENEW" my IP address. Also not sure how to access the router LOGs.
DI-604 router is at least 6 years old---
Thanks for any reply - hope to get back to this later today -

Unable to connect after modem and router restart

Hi Everybody
Some times i don't get any internet connection from my cable modem (Motorola 5100 surfboard). In such cases, Time Warner cable recommends restarting the modem. I am connected to the internet in the following sequence:
Cable Modem --> Router --> PC
The way it should work:
Switch off the router
Switch off the cable modem
Restart the cable modem (all the lights should be on)
Restart the router
Connected to the Internet!
However, things don't work this way. If I connect the PC to the cable modem directly after the modem restart, I am able to get online
If I try to connect with the router in the middle, I get no connection. Usually, I have to follow this sequence (instead of the one above):
Switch off the cable modem
Re-set the Linksys router (loose all my settings)
Switch off the router
Restart the cable modem (all the lights should be on)
Restart the router
Connected to the Internet!
Re-configure the router manually to get back my previous settings
Need your help to figure out why a simple re-start of the modem and router (in that sequence) doesn't work and I have to re-set the router to get on-line
One more thing - I backed up my router configuration (Administration --> Config Management --> Backup) and after getting online, restored it. Thought It would work, but no luck. Couldn't connect via the router. Had to follow the above sequence (again) to get online and then manually had to re-configure all router settings
Rourter - WRT54G. Version 2
Firmware version - v4.21.1
Any help is greatly appreciated. Thanks

Step should be :
1) Shutdown the computer.
2) Unplug the Broadband modem’s power cable and wait for 30 seconds.
3) Unplug the router’s power cable and wait for 30 seconds.
4) Plug in the Broadband modem’s power cable and wait for its lights to appear stable.
5) Plug in the router's power cable once the modem’s lights appear stable.
6) Power on the computer on and test the Internet connection.

Bluetooth mouse is not connected after reboot or bluez restart

Sometimes I see a paring request from the mouse. Sometimes authorisation request and if I go to the bluetooth settings it even propose to type a PIN code on the mouse )
Regardless my action after restart of bluez I am at the starting point.

I mentioned that, because this "solution" used to work for me on previous similar problems. After these steps the mouse used to autoconnect again after reboots and wakeups. Then after some weeks the problem appeared again.
Now this also doesnt work anymore. Now, everytime the mouse is disconnected, I have to push connect-button on the mouse and then manually initiate the connect process from the notebook (KDE: bluetooth applet -> Mouse -> Connect). It is not enough to just turn on the mouse.

Airport Express falls out after app. a day

Hi
My Airport Express is 2 years old and is suddenly begone to stop allowing connection after about a day. Then if you cut the power and again power it up it works just fine fore about a day or so. I have reloaded the firmware, and that did'nt change anything. My question is - do i have any options to fix it my self or should i just go buy a new device?
Sincerely
Kim

Welcome to the discussions, Kim!
It sounds like your AirPort Express is likely picking up some wireless interference from another wireless network near you, or even a nearby cordless phone.
Do you have AirPort Utility installed on your computer? It would be located as follows:
Macintosh HD > Applications > Utilities > AirPort Utility
Click Manual Setup
Click the Wireless tab below the row of icons
Look for the setting for Channel. It is probably set to Automatic now
Select another channel such as 8 or 9
Click Update to save your new settings
Give that a try. You may need to experiment further in order to find a clear, unused Channel. Keep trying different channels if needed. Hopefully, you will find a good one for your wireless network.

HELP! Gateway stops accepting new connections

Config: PS6.1 on Solaris 9 (Sparc), seperate gateway on Solaris 9 (Sparc) The PS6.1 was migrated from a PS3.0 installation, The machines are V240 with 2GB RAM and 4GB swap.
I start the GW with: ./S43gateway -n default start debug
Several minutes after startup (it varies from 1 to 40) I get the following message:
Class Name: com.sun.portal.rproxy.rewriter.services.idsame.IDSAMEDataServiceStub04/02/2004 07:29:07:823 PM CST: Thread[Thread-14,5,main]
ERROR: RemoteHandler : ERROR on remote machineAfter a while, something will trigger the following set of messages and that's when the gateway stops accepting new connections.
ESessionMsg caught exception when reading:

java.lang.OutOfMemoryError
        <<no stack trace available>>The OutOfMemoryError will keep coming out for a while, why it stops, I don't know. When this does happen, the java process is only using about 220MB of RAM and only about 10 users are logged-in.
This was working fine until we changed the IP of the gateway and moved its ethernet connection to "outside" the firewall. I re-installed the gateway software to make sure I didn't miss anything other than platform.conf. I have the webproxy enabled for the bookmarks channel and that is working. I have holes in the firewall for the proxy, LDAP and HTTPS ports.
Any ideas?
Thanks,

The gateway has to be tuned substantially to get good performance.
The tuning needs to be based on your load
e.g how many netlet connections, how many concurrent users you expected to handle etc ..
the default min heap size and max heap size need to change it. You can go upto a max of 2 Gb but I would recommend starting with a smaller heap size of 500 M and see how your performance goes.
The min and max heap size should always be the same for better performance. If your using netlets then you have to change the thread parameter. Each netlet connection uses two threads so if your using a large number of netlet connections then your thread count needs to 500 at a minimum to support 200 concurrent netlet sessions. Increasing the thread pool will also use more memory as each thread uses a min of 512 K of memory. The thread stack size needs to be set to 128 K.
These are the initial things to start with, you can also set jvm option -verbose:gc to enable gc logs. This will show memory usage.
These are good things to start with ..

WRT300N Stopped accepting wireless connections

I have a WRT300N, and last night, my roommates lost wireless connection. Our SSID still shows up in the site survey, with excellent strength, but the router has apparently stopped accepting wireless connections.
We have reset the router twice, reset to factory defaults, upgraded the firmware, reconfigured the wireless setup and they still cannot connect. Even when we turned off security, the connection process just times out.
It seems to me like the router is broadcasting the SSID, but the part that "listens" for incoming connections is broken.
What could be wrong? The router is only about 6 months old.

Hi... it seems to be a weird issue after firmware upgrade it should resolved the problem... anyways logon to router's setup page, try changing radio band to wide 40 Mhz, wide channel to 9, standard channel to 11, go to advanced wireless settings and reduce beacon interval to 50, fragmentation and RTS threshold to 2304 and setup WPA wireless security check whether it works or not and let me know...

On Mac - Android File Transfer stopped working.   It says Unable to connect after installing the Verizon Software Update Utility from phone.

    Hi JoeC695,
That's not good! We want your software to work properly. Have you tried uninstalling the Verizon Software Utility from your MAC? Do you receive a specific error message?
Thanks,
