hi since upgrading zope from 2.5.1 + zeo1, i've been having frequent zope/zeo 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 below[1] and the stupid.log[2] 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 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=12000) in the ENV, but running without is still the same. i've also tried runnin with -Z1, and -Z- also the same behaviour thanks for any help/pointers ------ ps axwf [1] # ps axf|grep py 17560 pts/0 D 0:00 \_ grep py 17160 ?
