Hello,
Might it be related to the problem I described in the thread "Tomcat
bottleneck on InternalInputBuffer.parseRequestLine" ?

Hi Anthony,
i have same problem sometimes in version 6.0.16, when the thread stuck
occurs again, execute the follow shell script, please adjust for your
scenario.
#!/bin/bash
today=`date +%Y%m%d%H%M%S`
psId=`/opt/java/jdk1.6.0_06/bin/jps | grep Bootstrap | cut -d' ' -f1`
/opt/java/jdk1.6.0_06/bin/jstack -l $psId >
/mnt/logs/stack/stack${today}.txt
execute some times, then post results here, for us to take a look,

Hello everyone,
I am having quite a weird situation on a production server : tomcat
seems to be stuck somewhere when handling http requests.
The activity being slow (10 users), some requests take exactly 30
minutes to be processed.
I have put aside the following :
-it happens on any page (not linked to a particular path)
-client issue : sniffing the network did not show anything special :
POST is ok, ACK is received by the client which waits for the server's
reply
-database lock : when that happens, I do not see any lock in the database.
-filters : we tried to deactivate all of them : same result
-I see no errors, warning or something significant in the log files.
I am wondering why I am having the 30 minutes delay... maybe someone
has encountered the same situation... Thanks in advance for helping me
on this one !
Anthony
