I'm running 1.6.0_18 under OpenSuSE 11.0-11.2 and I've only had one problem. It looks like a GLIBC error related to IPV6. I disabled IPV6 on the machine and it's been rock solid since. I don't use native connectors, or AJP. I do about 900,000 hits with 4GB/Day spread across 3 servers and it's just rock steady. I run the tomcat instances for 2-3 weeks each before re-starting. For each machine, that's about 6 million hits with about 40 GB of transfer.
