Thread application dumping on RH4


I don't know whether its the right place to raise this issue.

We are facing one strange issue. We have one messaging application that 
uses SonicMQ series CPP client libraries. We have one wrapper library 
built over it. We migrated that wrapper library from RH2.1 to RH4. We had 
built that library using -m32 flag. Now when we tried to run that 
application on RH4, we are facing following thread issue:

(gdb) where
#0  0xf772f3f3 in EqQueue<InboundMessage*>::InternalGetExistingItem ()
   from /apps/edgapi/
#1  0xf772ef5a in EqQueue<InboundMessage*>::GetItem ()
   from /apps/edgapi/
#2  0xf7725e18 in EdgEngineData::processInboundMessages ()
   from /apps/edgapi/
#3  0xf772601f in EdgEngineData::dispatcher ()
   from /apps/edgapi/
#4  0xf76b4e35 in EqThread::Execute ()
   from /apps/edgapi/
#5  0xf76b3d00 in EqThreadable::IndirectEntryPoint ()
   from /apps/edgapi/
#6  0xf76b3d76 in s_Dispatcher ()
   from /apps/edgapi/
#7  0x00381371 in start_thread () from /lib/tls/libpthread.so.0
#8  0x003179be in clone () from /lib/tls/libc.so.6

Now to solve this issue, we found out that if we set LD_ASSUME_KERNEL to 
2.4.19, it'll take old thread library and not the NPTL one. So we had to 
set that environment variable. Now the application runs fine but 
infrequently it dumps. The stack trace is as follows:

(gdb) where
#0  0xf79437c8 in java::lang::String::lastIndexOf () from 
#1  0xf7bccef0 in progress::message::jclient::DestUtil::getRoutingName ()

#13 0xf7547ffa in clone () from /lib/i686/libc.so.6

We also tried to directly run the binaries built on RH2.1, on RH4, but we 
face the same issues.
Do you have any clue regarding above issue ?? Any help or information 
would be appreciated.
