My server configuration is:
CVS 1.12.13 on Solaris 11.
My client configuration is:
CVS 1.12.13 on Debian 4.0
I am trying to check out a project containing multiple binary files each less
than 512 MB in size. The server reports the following error:
Nov 12 10:01:24 root cvs[879]: [ID 233912 daemon.emerg] error (1, 0) called
recursively. Original message was:
Nov 12 10:01:24 root cvs[879]: [ID 702911 daemon.emerg] cvs [checkout aborted]:
memory exhausted
Nov 12 10:01:24 root cvs[879]: [ID 587406 daemon.emerg] error (1, 0) called
recursively. Second message was:
Nov 12 10:01:24 root cvs[879]: [ID 702911 daemon.emerg] cvs [checkout aborted]:
memory exhausted
Nov 12 10:01:24 root cvs[879]: [ID 286756 daemon.emerg] Aborting.
The server reports sufficient physical memory available. Before:

No per-process memory limits appear to be set. However, the cvs process is
unable to memory-map the file:
mmap64(0x00000000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0) =
0x08430000
mmap64(0x00000000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0) =
0x08420000
mmap64(0x00000000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0)
Err#12 ENOMEM
mmap64(0x00000000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0)
Err#12 ENOMEM
Questions:
(0) Why is mmap64 failing in this case?
(1) Can the memory usage be limited?
(2) Can the number of files memory-mapped simultaneousely be limited?
