last posting (unfortunately as of 2001-10-24) in bug parade tells: "After
further investigation it seems we are dealing with
a libthread bug (4484522)  whereby the VM thread blocks in

I'm afraid it's not what you'd name a solution :-(

Unfortunately it's not a Solaris-only problem. Seems tomcat is a kind of
catalyser: we encounter a comparable problem under aix 4.3.3 (jvm 1.2.2 and
1.3.0, tomcat 3.2.1 to 4.0), and last tests here indicates, as far as I
understand, in assertion failure in some gc part :-( we are now waiting for
ibm move.
Our deployment is blocked by this bug, which seems (again as far as we
understand) to appear as faster as number of processor grow and cpu load is
low (that would explain why our heavy-loaded 2-proc dev machine crash in 25
days when a low-loaded 8-proc production machine crashed after 2 minutes,
and why we met it during deployment phase :-(( ).
