The client arch and software doesn't make a difference, the problem is on the server side. Problems seen when using opencvs server-side include giving out the wrong file version, and giving a checkout which can't reliably be used against a server running original CVS.

Or maybe back then the servers were all i386, too, and both client and server needed to be 32 bit? i.e., what used to be a client problem is now a server and client problem.

While processing RCS deltas, don't allocate twice as much memory as needed when copying a line vector to a vector which has less lines. Also, when switching back from a branch to trunk while searching an RCS file for a revision, free the trunklines vector immediately after lines saved in it have been copied back into the currentlines vector. Somehow, these two changes together make the problem go away. ok tobias@, this has been a serious annoyance sthen@, sure deraadt@ Members: src/rcs.c:1.22-1.23 - Hmm. Looking at the number of bytes in the error message which matches what's seen on anoncvs.usa and differs to my server... Todd, does the copy in your chroot pre-date this commit?

One problem solved. Sounds like the remaining issue is internal fragmentation, possibly exacerbated by randomization. How old is your cvs binary? I'm wondering if the realloc fixes I made last release have any effect. And of course, I think you can always up the ulimit.

Re: out of memory errors seen on several AnonCVS servers
I believe this problem ought to be fixed over the next few hours as mirrors pull updated files.
Re: out of memory errors seen on several AnonCVS servers
Summary of off-list mail exchange: anoncvs.usa consistently has a realloc failure in xenocara/font/misc-misc/18x18ja.bdf, some other servers have a failure the first time checking this file out when it's part of the whole directory, but resuming or checking out individually does work. $ cvs -d anon...@anoncvs.spacehopper.org:/cvs get xenocara/font/misc-misc U xenocara/font/misc-misc/10x20.bdf U xenocara/font/misc-misc/12x13ja.bdf cvs [server aborted]: out of memory; can not reallocate 3833880 bytes $ cvs -d anon...@anoncvs.spacehopper.org:/cvs get xenocara/font/misc-misc U xenocara/font/misc-misc/18x18ja.bdf U xenocara/font/misc-misc/18x18ko.bdf.xaa U xenocara/font/misc-misc/18x18ko.bdf.xab snip But against anoncvs.usa it always fails: $ cvs -d anon...@anoncvs.usa.openbsd.org:/cvs get xenocara/font/misc-misc/18x18ja.bdf cvs [server aborted]: out of memory; can not reallocate 5242880 bytes This only happens with the network protocol (either via pserver or 'cvs server' via ssh) not with local checkouts. Forcing a coredump when realloc fails results in the backtrace below. This file *can* be successfully checked out in a newer version of cvs (I built a vanilla copy from upstream's sources), I made a start at porting our patches across, but got stuck in a few places (and of course such a change would require *very* careful checking considering what we use cvs for).
