[Catalyst-dev] Re: Catalyst-dev Digest, Vol 63, Issue 6

[Joseph He]

Thank you, T0m. Actually it is 5.8.7.

I have done more testing while having windows Tast Manager open. I find out
that these issues only happen when I already have about 35-38 Perl processes
running. Mainly two types of errors:

1. [Wed Sep 29 15:06:11 2010] [error] [client 127.0.0.1] (OS 109)The pipe
has been ended.  : FastCGI: comm with server "C:.....fcgi" aborted:
GetOverlappedResult() failed, referer ......

## I searched and know that "(OS 109)The pipe has been ended" is SQL server
error message.

2. [Wed Sep 29 15:10:52 2010] [error] [client 127.0.0.1] FastCGI: server
"C:......fcgi" stderr: install_driver(ODBC) failed: Can't load
'C:/Perl/site/lib/auto/DBD/ODBC/ODBC.dll' for module DBD::ODBC: load_file:A
dynamic link library (DLL) initialization routine failed at
C:/Perl/lib/DynaLoader.pm line 230., referer: ....

So basically, when more than 35 Perl processes are launched, failure can
happen to any of my new scripts.

I tried to start some scripts as static server, say 20 scripts, then I will
meet the same problem when the processes number reach to 35ish or more. If I
try to initiate more than 40 as static server, in the initiation log, it
will show some warn message like "[Wed Sep 29 16:02:44 2010] [warn] FastCGI:
server "C:.....fcgi" (pid 6860) terminated with exit with status
'-1073741502'
[Wed Sep 29 16:02:44 2010] [warn] FastCGI: server "C:.....fcgi" terminated
with exit with status '-1073741502'.

It seems to me the total number of processes that can be run on windows
depends on CPU, Memory, etc. FastCGI can eat up system resources quickly. I
don't know whether this is a normal issue for fastCGI/Apache/Windows or
maybe this can be optimized by some configuration.

FYI: my PC is with 4G ram and Intel Core 2 T5600 @1.83G.

Really really appreciate some help!

 Joe
