Debian Wheezy FastCGI-PHG Problem

[fliegerhermi]

Hello everybody!
I am having the following problem: I am running a script that takes a while because it runs a module that does the customer-setup in Plesk.
At a certain point I get a bad gateway 502 nginx-error. It also crashes with nginx disabled. The apache error-log shows the following error:

[Mon Dec 02 09:36:12 2013] [notice] caught SIGTERM, shutting down
[Mon Dec 02 09:36:21 2013] [error] FastCGI process 5223 still did not exit, terminating forcefully

I changed some values of the fastcgi.conf in the mods-enabled dir of apache2, but it didn't change anything....

FcgidIdleTimeout 3600
FcgidIdleScanInterval 480
FcgidBusyTimeout 1800
FcgidBusyScanInterval 480
FcgidZombieScanInterval 12
FcgidErrorScanInterval 12
FcgidProcessLifeTime 0

# Change the rate at which new FastCGI processes are spawned under load. Higher=faster
FcgidSpawnScoreUpLimit 10

# Higher number = spawning more FastCGI processes decreases the spawn rate (controls runaway
FcgidSpawnScore 1

# Higher number = terminating FastCGI processes decreases the spawn rate (controls runaway)
FcgidTerminationScore 2

# Increase the FastCGI max request length for large file uploads (needed for some sites)
FcgidMaxRequestLen 1073741824

FcgidMaxRequestsPerProcess 100000
#FcgidMinProcessesPerClass 3
FcgidMaxProcessesPerClass 4
FcgidMaxProcesses 16
FcgidIOTimeout 1800


Does anyone have an idea on what the problem might be?

Thanks!
