As I described, the port 20000 hangs and a request to port 20001 did release the httpd.Since we moved to the new HW (same Solaris version) we httpd hangs many times per day.Before that, we experienced http hang outs but once every 3 months and a restart did solve the issue.I say that because the problem started to happen as soon as we changed our Solaris HW to a new one.Hi,After doing some search I suspect our problems to be related with this issue : https://issues.apache.org/bugzilla/show_bug.cgi?id=47645
Can someone confirm that it worth trying to rebuild with the above patch ?
