Hi, I have a Solr instance with 6M item index. It normally uses around 3G of memory. I have suddenly started getting out of memory errors and increasing the Xmx parameter to over 4G didn't fix the problem. It was just buying us time. Inspecting the heap, I figured that 90% of memory is occupied by FieldCache. Is this normal? We do very little sorting and no faceting.
Is FieldCache ever supposed to get cleared? Can this be done through HTTP? Do we need more memory? If so, I don't understand why the minimal set of changes we introduced (one multivalued field) would cause the memory to drastically increase. The communication with the Solr instance is done via HTTP.
