[Zope] zope-2.6.1+zeo-2.0.2 not trouble

[Bakhtiar A Hamid]

hi
since upgrading zope from 2.5.1 + zeo1, i've been having frequent zope/ze=
o=20
client hanging/not responding.

the setup:
we have zope-2.6.1-src + zeo-2.0.2 on linux with python 2.1.3

frequently, the zeo client hangs/not responding. output of ps axf is belo=
w[1]=20
and the stupid.log[2]=20

Also, nothing much in ZEO_EVENTS.log[3]

telnet localhost 8080
GET / HTTP/1.0\n\n
resulted in nothing.  no time out, nothing

running ./stop will only kill the parent process, i.e 17160 in the below=20
example.  the other processes can only be killed with a kill -9 17161.

restarting the zeoclient will make it respond again.

i've tried zeo2.1a1( iirc) and the behaviour is the same
i used to run with persistent zeo cache (ZEO_CLIENT=3D12000) in the ENV, =
but=20
running without is still the same.  i've also tried runnin with -Z1, and =
-Z-
also the same behaviour

thanks for any help/pointers
