service(indexer-worker): child 18977 killed with signal 11 (core dumped)
Hello to everybody,
first of all: thanks a lot for your hard work and for this nice piece
of software!
After many search about the following SIGSEGV, I decide to post the backtrace
and I hope to have avoided duplicated thread.
The problem arise after I enable clucene fts. I tryed the clucene ports version
(I am using OpenBSD) and a fixed version from github
(Blue-Rocket/clucene::feature/pod) which contains FreeBSD fixes and
others memory leak patches, but the problem persists.
I built either dovecot-* and clucene-core with -g and the following
logs are taken
from that version.
Maybe, I can do more debugging but I don't know how; some ideas?
thanks a lot

This is known issue at the moment and we are looking into it. Currently our only advice is to use something else, such as solr, for indexing, until we get this fixed. Aki
