Summary: All Tomcat http threads stuck in
java.net.SocketOutputStream.socketWrite0(Native Method)
Product: Tomcat 6
Version: 6.0.14
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]

stuck.
CPU utilization is close to nothing. After getting a thread dump from the
running java process, a following stacktraces are seen in all of the
http-threads:
Is anybody able to tell, whether this is a bug in Tomcat, JVM, in our
configuration or have I just diagnosed the problem incorrectly?
Something to workaround this problem?
