Hello,
I get the error "IOERROR: mapping index file for user.XXX: Not enough space"
when a client selects a mailbox. I've traced the process and it seems to be
a HPUX mmap problem when the imapd mmap's twice the index file of the
mailbox. How can I fix or workaround this problem ????
Thanks and sorry for my bad english,
Carlos.
My configuration:
HP-UX 11.0 (with PHCO_22923 last libc cumulative patch)
Berkeley-db-3.2
cyrus-sasl-1.5.24
cyrus-imapd-2.0.12

ERR#12 ENOMEM
Found in http://devresource.hp.com/STKL/impacts/i18.html :
HP-UX mmap() has several semantic differences from Linux mmap().
HP-UX mmap() does not currently allow:
-overlapping pages in any mmap() calls
-two threads calling mmap() on the same page
-an mmap() of /dev/zero to access anonymous memory regions.
-the mmap() of a page as MAP_SHARED more than once. In a multithreaded
program, or a function where the calling function may have mmap()ed,
MAP_PRIVATE must be used.
This functionality will become available in the core HP-UX after 11i.
