Hi, I have a perl based server that creates a TCP listen socket in a parent process, then forks off an N-child process pool that normally accepts connections round-robin style alla apache 1.3. Everything worked great when I was based on cygwin1.dll version 1.5.18. I would see many requests being simulatenously sometimes lasting up to a minute.
Then I did a recent upgrade and suddenly all requests became serialized. That is, an entire request would need to be handled before a pending one a child began. I immediately downgraded perl to 5.8.6-4 from 5.8.7-5. Nothing changed. Then I did a complete cygwin rollback and the concurrency went back to normal. I was then able to advance just the version of perl back to 5.8.7-5 and everything still works. After lots of back and forth, I was able to isolate the behavior difference to cygwin1.dll. I would really like to keep up with all cygwin changes but I am now stuck knowing there is a problem for me with the latest cygwin version. I realize that Perl's fork under cygwin is technically using threads so I left wondering if this is a blocking io problem (that changed with cygwin revs) since it seems to transcend perl. Any help is appreciated. Thanks, Chris __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
