SMTP postfix crashing - network_biopair_interop read timeout

Periodically, my mail server goes into a crash cycle. Error messages like those below appear, and very quickly, the machine becomes unresponsive (I believe because it can't fork any more process - so OD won't authenticate, and any command which requires authentication (like a restart or service restart) hangs indefinitely).
The machine will crash every ~12 hours after being rebooted, for maybe 2-3 days before the problem mysteriously goes into remission. I don't know what confluence of events causes this, or how to see it coming sooner so I can stop and restart the mail service.
Any insight or solutions would be greatly appreciated.

Thanks for your thoughts and time.

Crashes and read-only file systems

Notice: I apolgize for the long post, I've tried to be as thorough as possible. I have searched everywhere for possible solutions, but things I've found end up being temporary workarounds or don't apply to my situation. Any help, even as simple as, "have you checked out XYZ log, it's hidden here", would be greatly appreciated. Thanks
I'm not sure what exactly caused the issues below, but they did start to happen within a day of running pacman -Syu. I hadn't run that since I first installed Arch on December 2nd of this year.
Setup:
Thinkpad 2436CTO
UEFI/GPT
SSD drive
Partitions: UEFISYS, Boot, LVM
The LVM is encrypted and is broken up as: /root, /var, /usr, /tmp, /home
All LVM file systems are EXT4 (used to have /var and /tmp as ReiserFS)
The first sign that something was wrong was gnome freezing. Gnome would then crash and I'd get booted back to the shell with all filesystems mounted as read-only. I started having the same issues as this OP:
https://bbs.archlinux.org/viewtopic.php?id=150704
At the time, I had /var and /tmp as ReiserFS, and would also get reiserfs_read_locked_inode errors.
When shutting down (even during non-crashed sessions) I would notice this during shutdown:
Failed unmounting /var
Failed unmounting /usr
Followed by a ton of these:
device-mapper: remove ioctl on <my LVM group> failed: Device or resource busy
Nother of these errors had ever appeared before.
After hours of looking for solutions (and not finding any that worked) I was convinced (without any proof) that my Reiser file systems were corrupt and so I reformatted my entire SSD and started anew - not the Arch way, I know I set all logical volumes as EXT4.
After started anew, I noticed
device-mapper: remove ioctl on LVM_SysGroup failed: Device or resource busy
was still showing up, even with just a stock Arch setup (maybe even when powering off via Arch install ISO, don't remember). After a lot of searching, I found that most people judged it a harmless error, so I ignored it and continued setting up Arch.
I set up Gnome and a basic LAMP server, and everything seemed to work for a couple of hours. Soon after, I got the same old issues back. The System-journald issue came back and per the workaround on https://bbs.archlinux.org/viewtopic.php?id=150704 and a couple other places, I rotated the journals and stopped journald from saving to storage. That seemed to stop THOSE errors from at least overwhelming the shell, but I would still get screen freezes, crashes, and read-only file systems.
I had to force the laptop to power off, since poweroff/reboot/halt commands weren't working (would get errors regarding the filesystems mounted as read-only).
I utilized all disk checking functions possible. From running the tests (SMART test included) that came as part of my laptop's BIOS to full blown fsck. All tests showed the drive was working fine, and Fsck would show everything was either clean, or
Clearing orphaned inode ## (uid=89, gid=89, mode=0100600, size=###
Free blocks count wrong (###, counted=###)
Which I would opt to fix. Nothing serious, though.
I could safely boot back into Arch and use the system fine until the system decides to freeze/crash and do the above all over again.
The sure way of recreating this for me is to run a cron job on a local site I'm developing. After a brief screen freeze (mouse still moveable but everything is otherwise unreponsive) I'll systemctl status mysqld.service and notice that mysqld went down.
It seems that it's at this point my file systems are mounted as read only, as trying to do virtually anything results in:
unable to open /var/db/sudo/...: Read-only file system
After some time, X/Gnome crashes and I get sent back to shell with
ERROR: file_stream_metrics.cc(37)
RecordFileError() err = 30 source = 1 record = 0
Server terminated successfully (0)
Closing log file.or_delegate.h(30)] sqlite erro1, errno 0: SQL logic error or missing database[1157:1179
rm: cannot remove '/tmp/serverauth.teuroEBhtl': Read-only file system
Before all this happened, I was using Arch just fine for a few weeks. I wiped the drives and started anew, and this still happens with just the minimal number of packages installed.
I've searched for solutions to each individual problem, but come across a hack that doesn't solve anything (like turning off storing logs for journal), or the solution doesn't apply to my case.
At this point, I'm so overwhelmed I'm not even sure where exactly to pick up figuring this issue out.
Thanks in advance for any help

Did this occur when you booted from the live/install media?
What is your current set up? That is, partitions, filesystems etc. I take it you have not yet reinstalled X but are in the default CLI following installation?
If turning off log storage didn't help, reenable it so that you may at least stand a chance of finding something useful.
What services, if any, are you running? What non-default daemons etc.?
Does it happen if you keep the machine off line?
Have you done pacman -Syu since installation and dealt with any *.pacnew files?

Read Timeout is not working with business service in OSB 11.6

HI All,
We have set below configuration in "Http Transport Configuration" of a business service.
Read Timeout- 8
Connection Timeout - 8
Authentication - None
Proxy Serve
Follow HTTP redirects - Disable
Use Chunked Streaming Mode - Enable
Even though backend is taking more than the configured value in Read Timeout but timeout is not happening in OSB, Connection time out also not worked, when we tested with wrong backend URL.
Any help for this configuration would appreciated.
Thanks,.

Hi,
Have you invoked any Services before calling the Business Service.
If Yes, then the problem with the Invoked service.In this scenario even if you set the time out period it will not work..
If No, your request payload is high

RT FIFO Read timeout

I have a timeout question about RT FIFO Read in Producer/Consumer system. Here is the scenario.
Producer writes data to RT FIFO via RT FIFO Write;
Consumer read data from RT FIFO via RT FIFO Read with timeout 100ms;
If RT FIFO is empty, returns 100ms timeout and stops Producer and Consumer.
If RT FIFO is not empty, process the data from FIFO and continue Producer/Consumer.
As I understand, RT FIFO empty means 100ms timeout. But the 100ms timeout condition does not behave properly as expected.
Am I understanding the FIFO Read timeout correctly?
Thanks!

OSB Business Service is not timing out on Connection/Read timeout

I have a weird problem with my business service in OSB. I have set the read timeout value as 1 sec and Connection timeout value as 1 sec. The response from backend is taking more than 2 seconds or even 3 seconds but still my business service is not timing out..! My service is still listening to the response from backend even if it comes after 3 seconds. I expect it to timeout after 2 seconds. Any ideas?
Business Service Configurations:
Service Type: Any type
Protocol: http
Retry count : 0
Retry Application Errors: No
Read Timeout: 0
Connection Timeout: 0
HTTP Request Method: POST
Result Caching: No
Let me know if you need any more information. Thanks in Advance.
Regards
Kaleem

AbhishekJ wrote:
Maximum possible successful response time of the service will be less than Read TO + Connection TO.
Alas, this is not true.
Maximum possible response time is infinity.
There are two reasons for that.
1. Read timeout is not counted as time from the successful connection establishing to the current moment. It is measured as time from the last received byte to now. Imagine a backend service that sends a single byte in a data packet every 500ms. Despite you have read timeout set to 1, the receiving of 3K message will take 25 minutes, and yet your Biz service will not timeout.
2. In HTTPS, handshake is handled by a separate library which has its own quirks. Specifically, if the key exchange is broken at particular point of handshake, the library re-establishes the connection and does it few times; in my experiements, the largest I could delay the eventual fault was about 3 minutes.
Having said that, in the OP message the configuration is Read=0, Connect=0, so I wonder why the timeout is expected.

Read Timeout on non-blocking sockets

Hi,
I was wondering if there is a way to specify a read timeout (like setSoTimeout for synchronous sockets) when using a non-blocking socket.
I'd like to have the select() method return is a sockets timeout expires, puting in the selected key set the timedout socket and have it's read operation return -1, something like what happens when a socket is closed by the other side.
The thing is I need this to be a timeout specific to each socket, thus the select(millis) isn't apropriate.
Anyone knows of something like this?
Thanks....

Yeah, select() is the only thing built in for that, and you have to do the bookkeeping yourself. You would start something like forming the disjunction of the ready keys and the registered keys after each select, to get the unready keys, and then looking at their history to see how long they have been unready via a Map{key,Long(time)).

read-timeout-seconds not working

(WL 5.1, SP 11)
Hi all,
I'm playing around with Read-Only entity beans, and I get a problem
with the read-timeout-seconds property. I've set my
weblogic-ejb-jar.xml like this:
<ejb-name>product.entity</ejb-name>
<caching-descriptor>
<max-beans-in-cache>1000</max-beans-in-cache>
<cache-strategy>Read-Only</cache-strategy>
<read-timeout-seconds>60</read-timeout-seconds>
</caching-descriptor>
The first call to the EJB caches the database record, and subsequent
calls use the cache. My problem: Even if I delete the database record
directly (I know, I shouldn't do that... but like I said, I'm playing
around here... ;)) and wait for more than 60 seconds, the next call to
the bean still returns the same cached entry.
I tried with <idle-timeout-seconds> set to 60, and it doesn't work
neither.
I've seen in previous messages that this problem (or similar) was
fixed in SP4, but I use SP11, so it shouldn't be the problem.
Thanks for your help!
Phil

Modbus TCP/IP read timeout

The code below was taken from the NI Modbus library:
The first TCP Read VI, reads 7 bytes as a binary string. The data string is then cast to the MBAP_Header data type.
The MBAP header contains a length field, that is used to determine the length of the Modbus PDU (i.e. remaining part of the TCP message)
The second TCP Read VI then gets the remaining part of the message.
Can I set the second read timeout to 0?
For reqular Ethernet, the maximum packet payload is 1500 bytes.
1500 bytes is larger than any Modbus message, so I would not expect segmentation of Modbus messages.
Is this correct?
In general, if the application data is less than 1500 bytes (on regular Ethernet) and data is read in two parts, is it a good idea to set the second read timeout to 0.
Is there any other reason why I should not do this?
Thanks.

Hey,
The second read should not have a time out of 0. The first read only gets the first 8 bits of data, it does not buffer the rest of the package so the second read still needs time to receive the remaining data and hence will need at least some sort of time out value.
On the subject of segmentation, I believe you are correct. As long as your message doesn't excede 1492 bytes (I think the 1500 includes the overhead of the Ethernet package), it should come down in one package.
The best thing you can do is to try it out.
Kind regards,

How to run vi continuously when VISA read timeout happens

Hello,
I am using LabView 2010 to read an Agilent 6000 series Oscilloscope. The Oscilloscope reads data from another experimental machine which fails occasionally due to sample failure. When the machine fails, it stops sending signal to the oscilloscope and leads to the VISA read timeout error and the whole vi is terminated. Is there a way that I can continuously run the vi when the error happens? For example, when the error happens, it stores the error in the error wire. When the vi read the error code from the wire, it sends a command to stop my experimental machine then stop the vi.
So far, it just simply stops during executing the visa read function. In this case, why do we have error in and out? The vi simply stops when the error happens.
Thanks
Lawrence
Solved!
Go to Solution.

I'll start of with automatic error handling. By default, LabVIEW enables the automatic error handling. So consider the case like the one below,
If let's say the VISA Read returns an error, but you did you pass the error information to VISA Close, what will happen is that LabVIEW will highlight the VISA Read (since the error comes from that function), pause the execution at the VISA Read and an error dialog box will appear. From the dialog box, it will prompt to either continue (Move on to the VISA Close) or stop (LabVIEW will stop the VI at VISA Read)
Now, consider another scenario like this,
By passing the error information from one function to another, let's say if VISA Read returns an error, that error will pass to VISA Close and finally to Simple Error Handler.vi. So Simple Error Handler will generate error dialog box after all the VISA operation is completed. This is called manual error handling (It can be enabled by just wiring the error information from one function to another and terminates at Simple Error Handler).
http://www.ni.com/gettingstarted/labviewbasics/handlingerrors.htm
As for VISA Close, here is the information about VISA Close.

Updated iPad2(2011) to iOS8 now iBooks crashes while reading a book. What is going on?

Updated iPad2(2011) to iOS8. Now iBooks crashes while reading a book and closes down. I have sync'd the iPad a few times but nothing changes and it will 'crash' every 5-10 minutes. What is going on?

A better solution. This worked for me and several others, from a post from MrsMike921 in the following thread:
https://discussions.apple.com/message/26725105#26725105
go to your settings, and first go to Safari and delete your history by scrolling down to "clear history and website data". Then go to the advanced settings and select ""website data". It should show 0 bytes. If not, clear again.
next go to iTunes and App Store in settings, and touch your Apple ID, the select sign out.
AFter you you sign out of your ID, restart your iPad by holding down the power button and home key simultaneously until you see the apple logo after the restart.
when you are powered up, go to iBooks. You should get a message that you need to sign in to sync up your books. Sign in, and that should do it.

Read-timeout-seconds

Hi!
What happens if I set <read-timeout-seconds> to some value
for a read only bean, according to bea's docs the ejbLoad() is called initially when the EJB is created and afterwards, WebLogic Server calls ejbLoad() only at intervals defined by the read-timeout-seconds. Does this mean that Weblogic always runs ejbLoad() every x seconds or ONLY if some client runs findByPrimaryKey() and the interval has expired?
Thanks,
A.

It's done lazily. When you access the bean, WLS checks if currentTime -
lastLoadedTime is > read-timeot-seconds. If so, it calls ejbLoad.
