We have enabled MDB_WRITEMAP on our HP-UX 11.23 Itanium after previous
discussions on the list, and that worked nicely for the most part.
However now we face a different issue: Occasionally, mdb_txn_commit will
return "Resource temporarily unavailable". I have not been able to
determine exactly which resource it's talking about; I suspected shared
memory limits, but raising this limit did not solve the problem. This
issue did not occur without MDB_WRITEMAP.
Any idea what else it could be? I can probably insert debug code into
LMDB if that's needed.
The only thing that can return that error is a syscall, and the only
syscall performed with WRITEMAP is msync(). I suggest you start looking
there.
