I have a java program running the IBM jre that scrolls through a list of urls displays them and then starts all over again. The thing will run for about 3.5 days and then choke. The javacore file provided by the jre has this at the beginning whith a whole bootload of stuff: SIGSEGV received at befff800 in /lib/libpthread.so.0.

Someone in the IBM java newsgroup suggested that I upgrade the kernel: ..................from IBM java NG post I've heard tell that there are memory leaks in several of the 2.2.x series kernels. You might try upgrading to 2.2.14-1.3.0 which resolves most of these issues(I've been liking it at least) That might explain your problem, but then again, I can't get Tux to work with Mesa & Plib. .................end from post My questions are: What the heck does libpthreads.so.0 do? Is upgrading the kernel going to help? Is there a newer glibc that will work with a machine that has been upgraded from 5.0 to 5.2 to 6.0 and all the updates I could find? Would starting over from scratch on this config with say, 6.1 help? This is no trivial matter since there are a multitude of config tweaks I have done over the past year or so on this machine but I suppose I can wade into it if it will help. Bugzilla has several mentions of glibc fixes but it didnot look like they were related to my problem but I am certainly over my head in really determining that. Any help appreciated. Bret
