hi,

i'm using mod_fcgid to run php as a suexec cgi on a debian lenny system.
mod_fcgid version is 2.2 (from debian). although everything seems to
work basically i'm seeing lines like this

[warn] mod_fcgid: stderr: Cache unable to open file for writing:
cache/956287ab2d93bc91ee48c8b4204c93f1

in apache error log. i don't know where this is coming from nor where to
configure anything concerning "cache". on a centos system with a similar
setup i don't have this problem. since i sometimes experience memory
exhaustion problems on the debian system i would like to know if the
above error.log message could be related to them.

thx for advice
matthias

you probably already knew this, but your CGI application is writing
this message to stderr, and mod_fcgid is capturing and logging it;
httpd/mod_fcgid don't generate this message

try searching for the message (starting with "Cache unable"); I just found

you're probably right. i was already suspecting something like this and
should've paid more attention to "stderr".... probably it's just wrong
permissions on a directory in some users webspace and not related to my
memory problems

thx

I think your mod_fcgid's IPC dir is not writeable. Check its permissions.
