  • webserver timeouts

    over the past days I've checked everything and tried to optimize apache, mysql unfortunately without success.
    Would it be possible to order a payable investigation?

  • webserver timeouts

    - IMSCP: 1.4.3
    - Distribution: Debian 8.6

    a few days ago I have already reported about apache and nginx timeout issues, after the update (1.3.16 > 1.4.3) nothing has changed.
    these are local timeouts that only affect apache, nginx and the monit server.
    So I need to use monit for restarts:
    if failed host localhost port 80 protocol http then exec "/usr/sbin/apachectl graceful"
    I also run curl response tests via cron (1min) from my local system, sometimes it works for many hours but usually there are interruptions.
    Following response outputs were generated while monit restart were deactivated:


    Lookup time: 0,012
    Connect time: 0,025
    PreXfer time: 0,199
    StartXfer time: 0,216
    Total time: 0,216


    Lookup time: 0,012
    Connect time: 1,021
    PreXfer time: 1,214
    StartXfer time: 1,261
    Total time: 1,261


    Lookup time: 0,012
    Connect time: 64,387
    PreXfer time: 64,559
    StartXfer time: 64,576
    Total time: 64,576


    Lookup time: 0,014
    Connect time: 64,857
    PreXfer time: 65,024
    StartXfer time: 65,042
    Total time: 65,042


    Lookup time: 0,012
    Connect time: 15,454
    PreXfer time: 15,632
    StartXfer time: 15,649
    Total time: 15,649


    during a timeout apache, nginx and monit server could also re-activated by service imscp_panel restart ....

  • update from 1.3.16 > 1.4.3 postfix auxpropfunc error

    update went well without any problems but now I see many auxpropfunc error in journalctl


    Code
    1. journalctl -p err -b
    2. May 07 11:43:03 host2 postfix/smtpd[23315]: sql_select option missing

  • Recommendation - http timeouts and ERR_CONNECTION_TIMED_OUT

    it seems sometimes there are conflicts w/ nginx and or php5-fpm, if I restart nginx and php5-fpm, apache2 is also back online ...


    and sometimes an nginx restart shows this error message:

  • Recommendation - http timeouts and ERR_CONNECTION_TIMED_OUT

    CPU load looks good ... no zombies and nothing special in our error logs, v3.16 was always very reliable so far ...


    for testing I have set a higher value for fs.file-max = 4097152 and reduced open-files limits in my.cnf
    there were no problems at night, but I guess it starts over when customers working on their applications ;-)


    ### edit ###
    yep, have to update - looks like the vlogger issue

    Code
    1. [Wed May 03 08:37:23.925425 2017] [mpm_worker:notice] [pid 24236:tid 140630988191616] AH00295: caught SIGTERM, shutting down
    2. [Wed May 3 08:37:23 2017] [notice] vlogger: caught TERM, shutting down
    3. [Wed May 3 08:37:25 2017] [notice] vlogger: DBI usage tracker dump interval set to 30 seconds
    4. [Wed May 3 08:37:25 2017] [notice] vlogger: started CustomLog Handler -- resuming normal operations

  • Recommendation - http timeouts and ERR_CONNECTION_TIMED_OUT

    ### Note ###
    I will not be able to do the update until the weekend ...
    But I recognized that a certain error message appears in the daemon logs before it freezes:


    Access denied for user 'web757'@'localhost' (using password: YES)


    after that I see also a DBI connection error for the imscp_user connection
    and mostly the panel is also frozen so I have to restart nginx, panel and apache.


    The system has been running smoothly for about 5 months without any problems, so it could be caused by a customer script ...
    above database connection access for web757'@'localhost') was set to % by the customer

  • Roundcube Plugins - Error

    because of a planned imSCP upgrade I updated my plugins first ... letsencrypt went well but roundcube plugins did not ...
    should I re-install the previous version of RoundCubePlugins 1.2.6 or is there any other way to fix this?
    Before I can run my imSCP upgrade I have to do some testing in a V-Box ... is there any soltution for a quick fix?
