I'd like to draw your attention to a problem report I sent in a while back, namele Problem Report kern/22826 "Memory limits have no effect in linux compatibility": http://www.freebsd.org/cgi/query-pr.cgi?pr=22826 As it turns out (see the above URL), it is not quite obvious that this has anything to do with linux emulation per se, being more of a problem with the vm code in the freebsd kernel. However, I have discovered a new fact that *may* point to an emulation problem: As I state in that problem report, Acrobat Reader version 4.05 just gobbles loads of memory, typically growing by a couple of megabytes for each page visited, if I select a zoom factor to make the page as wide as the screen. This can go on until the machine runs out of virtual memory, unaffected by rlimit settings. The curious thing is that the same program runs fine on real Linux, never growing beyond 19 MB in one test I ran. This happened with the very same binary, but of course it may be that the problem lies with a version of the runtime libraries in /compat/linux/ on my freebsd machine. Before I invest lots of time and energy into investigating this phenomenon in more detail, has anybody else run into this problem, or have any thoughts on it? - Harald To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
