I ran a mission critical web-app using Apache2/mod_perl2, and an sql database on Opteron using FC2 with non-threaded perl 5.8.5. I built apache, mod_perl, and perl from source. We didn't have any 64-bit related problems with the web app. The opteron is a very fast machine. Now, to go off the mod_perl topic for a few sentences, we did experience some crashes due to i/o intensive batch operations. The code was opening thousands of file handles very quickly. I found one relevant link on google which unfortunately I don't have access to anymore, but it cited a crash occurring while using bonnie++ for benchmarking on opteron. We had another issue with occasional segfaults of long running (7+ days) programs which consumed enormous (15G+) amounts of memory. Suffice to say though, we were going beyond normal usage, and encountered a few dragons. -- Report problems: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html List etiquette: http://perl.apache.org/maillist/email-etiquette.html
