SA TIMED OUT errors

Hello!
I'm getting the following "SA TIMED OUT" errors in my amavis.log file and would like to solve the problem. The time outs seem to causing delays in the processing of mail. I have upgraded clamav to use clamd as per Alex's tutorial at topicdesk.com and that seems to be working ok.
Here are a few of the errors extracted from the log file...

Hi Alex
Thanks for your reply - when I originally looked it appeared that perl was sucking up CPU resources, although I didn't check using top -o cpu at the time. Since posting my original message above I turned off some options in my local.cf file which fixed, or more accurately "bypassed" the problem. Not really ideal but it stopped the backlogging of mail - I'd rather fix it if I could.
The changes I made in the local.cf file were:

  • Timed out error in SRM

    Hi
    I am working in SRM 5 and with support level 9.
    When the user try to type in lot of information manually in the Header or the Item text in the SRM PO and then try to save it, he gets the SRM timed out error. Looks like SRM doesn't treat the information being filled in header and item text field as system being active and ultimately gives a timed out error.
    Any suggestions to overcome this issue?
    Thanks a lot in advance.

  • Timed Out error while executing BI report in Portal

    Hi Experts,
    When we are trying to execute a BI report which returns over 9 lac records, it is taking lot of time to get executed and then its throwing the timed out error.
    Can anyone help me resolving the issue?
    Is this a problem with the performance of Portal server or its just due to the huge amount of records that are being retrieved?
    Thank You.
    Regards,
    Murthy.

    I havent got any solution regarding this. But, due to constraint regarding number of open Question in the forum, I am closing this and as there is not other way I am marking it as answered.
    Please suggest any other way to close the thread if this is not the right way.
    Thank You.

  • Timed Out Error while waiting for response from DB Procedure

    Hi Gurus,
    We are encountering a problem in our production environment. The system is implemented using AIA foundation pack 2.5 on SOA suite 10.1.3.4.
    We have a BPEL process A which calls an ESB Service which inturn calls BPEL Process B. In process B, we have a DB procedure call which waits for a response from
    a DB procedure. The procedure doesn't reply on time and Process B remains in waiting state to get the response from DB Procedure wherein Process A errors out by showing as "Timed Out Error".
    This issue is intermittent and we have already increased transaction-time outs in transaction-manager.xml to 7200 and ejb-orion-jar.xml to 3600.
    When we encountered this problem, we found out that there are too many connections open and when we bounced the server, everything was restored to nornal but as it is a production env. we can't do it over and over again.
    We have 2 nodes each having max connections as 100 and min. as 0.
    Is there a limit to max no. of connections or can we do something in DB side to ensure that it doesn't happen again ?
    Please suggest.

  • Read timed out error while opening monitor tab in DataServices

    Regards,

    Hi Babu,
    you might try the following on the server where the problem occurred: call transaction SMICM -> Goto Services -> Select the service you are working with ->
    Service Change -> increase value for "Max. Processing Time"
    In case your application still times out you should see the changed value displayed.
    Sometimes just executing the application again 2-4 times might help, because compiling might happen and is taking some time in the system.
    With regards to parameters see also SAP Note [824554|https://service.sap.com/sap/support/notes/824554].

  • "TNS-12535: TNS:operation timed out" error after listener restart

    I have two related questions:
    Scenario 1:
    1. I have two remote Windows machines with database on each. One is Win 2003 Server (machine A) and another one is Win XP (machine B)
    2. I can ping from A to B.
    3. I can ping from B to A.
    4. I can tnsping from A to B.
    5. I CAN'T tnsping from B to A.
    6. Windows Firewall on both machines are off.
    What could be possible reason for point# 5?
    Scenario 2:
    Now, the second part:
    1. I had an unwanted entry in tnsnames.ora on B which I removed.
    2. Then I restarted the listener on B. Actually, I wanted to restart the one on A to check if that resolves issue mentioned in point# 5 above.
    3. I tried tnsping from A to B but suprisingly it is also giving "operation timed out" error now. So now tnsping not working from either sides.
    I didn't make any changes in listener.ora on B, just stopped it and started again. Only change made was removing unwanted entry in tnsnames.ora on B.
    Why does that affected database connectivity from A to B which was working fine previously?
    If any extra information needed please let me know, and thanks in advance for your answers.

  • I get a connection timed out error when trying to connect to the itunes store, if I have pending downloads they show up and I can download, also I was able to access my account, yet I can't access other parts of the store, I am in greece on a macbook pro

    I am from the states and am in Greece on vacation.  I have a good wifi connection yet keep getting a connection timed out error when I try to access the itunes store.  It is funny because pending downloads show up in the cue, and they download no problem.  I can also open my account.  When I try to go the the movies or music section of the stor though it just times out.  I tried updating to the latest itunes software and restarting, also I checked all the proxy boxes in the network section of the settings then unchecked them all and restarted and it keeps doing the same thing.  Any help would be appreciated.
    Thanks

    Welcome to AD!
    There's been plenty of posts about Norton & the removal tool here. Unfortunately many folks seem to not even know it comes pre-installed on most PCs! Even a trial version, never used or long since expired can cause problems - and not just with iTunes.
    Anyone with a Dell, HP, Gateway EEE PC, Asus ..... what Windows PC manufacturer does NOT have this junk software pre-installed?
    Almost all of them have made deals with Symantec to pre-install it.
    Horrible, horrible software.
    Anyway, glad you finally solved your problem.

    I've been REPEATEDLY getting "Network connection timed out (Error -3259) for two specific TV shows I'm trying to download. Other shows and songs are downloading just fine, which indicates there is nothing wrong with the network.
    I have already tried deleting the temporary files from the DOWNLOADS folder, but no luck.
    I have also tried restarting these two epispodes DOZENS of times.
    I've heard from various web sites that Itunes will not work properly with internet service from Time Warner. Is this true? I have no way to change my ISP as TW is all that's available to me.

  • Samba and fusesmb: "connection timed out" error

    Hello to everyone!
    I'm facing a weird problem here: since a couple of days I cannot use fusesmb anymore: I can still "see" the SMB network shares that are present on my LAN, but as soon as I try to enter one of those I get a "connection timed out" error.
    First of all I tried to reinstall fusesmb, to no avail. Then I tried to use smbclient directly:
    [tudhalyas@paranor ~]$ smbclient -L <my_windows_box_IP>
    This command correctly shows the list of shares that are present on my winXP box, and
    [tudhalyas@paranor ~]$ smbclient \\\\<my_windows_box_IP>\\SharedDocs
    creating lame upcase table
    creating lame lowcase table
    Enter tudhalyas's password:
    Domain=[WINBOX] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]
    smb: \>
    allows me to go into the "Shared Docs" folder of the said computer. From here I can flawlessly download files from the share.
    Reading this thread I thought that samba 3.5.1 could be the culprit, and so I compiled samba 3.4.7 through ABS and then installed it. Sadly, fusesmb still doesn't work. I even tried to use smbnetfs, but again to no avail.
    Does anyone of you know what I could do to address this issue? Thanks in advance!

    bump... can anybody help me please?

  • HT1386 Help iphone won't connect - "device timed out" error AGAIN & AGAIN

    I recently updated my phone to IOS 7.02 and now when I try to connect to itunes I get a "device timed out" error.  Thinking it must just be my itunes out of date, I updated it too.  Again and again the " device timed out" error still happens.  What an utter mistake to have loaded the new IOS.  I have scoured the help files, I have looked at hundreds of discussion threads - nothing.  The only thing I find is many many people seem to have this issue and no one can get it solved.  obviously Apple doesnt give a crap if you are forking out every 6 months.

    Hello,
    I would run through the troubleshooting steps in the following document - which one you choose depends on the operating system you're running. You've already done some of the early steps such as updating iTunes, but there are a couple of other steps you can try, such as verifying Apple Mobile Device Support is installed:
    iOS: Device not recognized in iTunes for Windows
    http://support.apple.com/kb/TS1538
    or
    iOS: Device not recognized in iTunes for Mac OS X
