Hi,
it is solved. It might be caused by a combination of several reasons - be
careful about proper settings and the name of ReadWritePaths attribute,
then check rights for tomcat user. Some troubles might be causes by
"OpenJDK 64-Bit Server VM warning: Failed to reserve shared memory. (error
= 12)" from SOLR - then add in solr.in.sh:
GC_TUNE=('-XX:+UseG1GC' \
'-XX:+PerfDisableSharedMem' \
'-XX:+ParallelRefProcEnabled' \
'-XX:MaxGCPauseMillis=250' \
'-XX:+AlwaysPreTouch' \
'-XX:+ExplicitGCInvokesConcurrent')
and also increase the SOLR file limit (another warning) in
/etc/security/limits.conf
Thanks
Jan
