Description Noriko Hosoi 2016-04-12 21:46:41 UTC
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/48383

db2index currently allocates a buffer as a derivative of cachememsize.

This value should be independent for the index process and documented clearly, so that server re-tuning isn't needed just to run db2index.

See  ./ldap/servers/slapd/back-ldbm/import.c:48:    job->fifo.bsize = (inst->inst_cache.c_maxsize/10) << 3;
