Hi Everyone,
I am seeing strange behavior in the way threads are switched in java
1.1.7v3. This is on a RedHat Linux 6.0 system (kernel 2.2.5-22, with
glibc 2.1). I have the jdk and native-threads packages for glibc on X86
from blackdown.org.
Problem 1: If I start 3 threads at the same priority and none yields or
blocks on i/o, only the first one to be started gets time. On a Solaris
machine the three threads share time roughly equally. Is this known
behavior? Is there a way to choose a different model? I should say
that this is using green threads.
Problem 2: I tried doing the same thing using native threads, in the
hope of getting a better time-sharing model. When compiled and run with
native threads, the behavior is strange enough that I think there must
be a library mis-match. The main routine usually doesn't sleep for 10
seconds when it is sent a sleep(10000l) (it sleeps for more like 100ms,
but very occasionally it will sleep for 10 seconds). Can I re-build the
native threads part from sources? Or is there a known library problem
with glibc2.1?
thanks in advance,
Rich
