    Version Parallels Plesk Panel v9.5.2_build95100504.17 os_Debian 5.0
    OS Linux 2.6.18-028stab068.9


    Looking into /var/log/sw-cp-server/error_log :
    I have the same error : [ERROR]: spawning fcgi failed

    Any help would be much appreciated.

    Best Regards

    Probably need more memory on your server: Cannot allocate memory on unix:/opt/psa/tmp/sw-engine.sock-0

    How much memory you have now?

    Hi

    Thanks for your reply

    It's a virtual server with 2 Gb of memory (burstable up to ?); a previous server with less memory was running normally and never crashed, can't understand.

    You should check resources from Virtuozzo side if it is Virtuozzo VPS.

    Hi

    I do not have acces to virtuozzo (hosting company restriction), is there another way to check this ?

    You can check output of free command at least. If it is UBC (not SLM) configured VPS, you can check failcounters with
    Anyway only provider can increase resources for your VPS.

    I asked my provider and he increased my ressources. He answred that I've exceeded the number of allowed TCP connections, I have 20 websites on this server most of them have max 50 visits/day two websites generates up to 300 visits/day. Can it be something maliciuous !!??
