Subject: zombie problem at UNIX IOC

Dear Sir/Madam,

I have zombie problem at UNIX IOC. 
Pthread is analog of VxWorks task. When IOC receives the request for
operating with PV,  iocCore spawns the pthreads: "CA event", "CA client".
Which is completed by "exit()" call or "return ()", this operation
switches pthread in  zombie state. iocCore contains following list of
pthreads:

__01.)_____tid=51___name=taskwd____PRI=4.
__02.)_____tid=54___name=cbLow____PRI=16.
__03.)_____tid=62___name=cbMedium____PRI=16.
__04.)_____tid=56___name=cbHigh____PRI=16.
__05.)_____tid=36___name=dbCaLink____PRI=15.
__06.)_____tid=78___name=ts_Casync____PRI=16.
__07.)_____tid=48___name=scanOnce____PRI=16.
__08.)_____tid=77___name=scan1000____PRI=16.
__09.)_____tid=50___name=scan500____PRI=15.
__10.)_____tid=55___name=scan200____PRI=14.
__11.)_____tid=53___name=scan100____PRI=13.
__12.)_____tid=49___name=scan50____PRI=12.
__13.)_____tid=31___name=scan20____PRI=11.
__14.)_____tid=32___name=scan10____PRI=10.
__15.)_____tid=67___name=CA TCP____PRI=13.
__16.)_____tid=66___name=CA UDP____PRI=10.
__17.)_____tid=37___name=CA online____PRI=10.
__18.)_____tid=68___name=CA client____PRI=12.
__19.)_____tid=76___name=CA event____PRI=11.
__20.)_____tid=75___name=CA client____PRI=12.
__21.)_____tid=74___name=CA event____PRI=11.
__22.)_____tid=73___name=CA client____PRI=12.
__23.)_____tid=72___name=CA event____PRI=11.
__24.)_____tid=71___name=CA client____PRI=12.
__25.)_____tid=70___name=CA event____PRI=11.
__26.)_____tid=69___name=CA client____PRI=12.
__27.)_____tid=38___name=CA event____PRI=11.
__28.)_____tid=57___name=CA client____PRI=12.
__29.)_____tid=64___name=CA event____PRI=11.
__30.)_____tid=63___name=CA client____PRI=12.
__31.)_____tid=59___name=CA event____PRI=11.
__32.)_____tid=65___name=CA client____PRI=12.
__33.)_____tid=58___name=CA event____PRI=11.
__34.)_____tid=79___name=CA client____PRI=12.
__35.)_____tid=80___name=CA event____PRI=11.
__36.)_____tid=81___name=CA client____PRI=12.
__37.)_____tid=82___name=CA event____PRI=11.
__38.)_____tid=83___name=CA client____PRI=12.
... ...
But all threads("CA event","CA client") from iocCore has zombie state.
Would you help me do this problem?


Best Regards,
Tatiana
