Description Byron Miller 2004-07-02 13:06:48 UTC

Description of problem:

large amount of threads over tcpip seems to cause the kernel messages 
and thus apps don't gracefully finish or throw errors because they 
can't get the network resource needed

Version-Release number of selected component (if applicable):

Fedora Core 2 - using latest kernel to fix J2ee errors (java getting 
stuck)


How reproducible:

Under load - Running a "crawler" to fetch 4 million urls of about 
200+ threads and it shoots this error on a HT 2.6ghz p4.  It seems to 
run fine on a dual xeon running the same code/kernel & os patches


Steps to Reproduce:
1. do a large web crawl (specifically nutch) with high thread count 
(http)
2.
3.
  
Actual results:

Comment 1 Dave Jones 2005-01-14 05:42:58 UTC

this should have got fixed in a subsequent kernel update.
can you confirm the latest updates have this fixed please ?

Comment 2 Dave Jones 2005-04-16 06:10:14 UTC

Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
