The kernel is from the simple dir on oss. With a 3rd Sept CVS 2.4.8 kernel under no load the pthreads program runs ok, but under load (a big rm -rf over NFS for instance), it fails like above, or fails like: % ./blah pid=681 Init mutex pid=681 About to create thread: mythread pid=681 about to cond_wait for mythread init 1. Segmentation fault (core dumped) % Also I found I could only build X natively on the Indy by disabling the pthreads parts; and maybe it's a similar 'Illegal Instruction' error in the 'conftest' program that seems to be stopping mozilla from building?? (at least under kernel 2.4.3 which otherwise seems more stable than 2.4.8) cheers, robin
