> {noformat}
> Run on a powerful server with 32 cores, 265GB RAM.
> The problem is that time to time it start to get very slow to update solr documents, for example time out after 30 minutes.
> document size is around 20k~50K each, each http request send to /update is around 4MB~10MB.
> /update request is done by multi processes.
> Some of the update get response, but the differences between "QTime" and http response time is big, one example, qtime = 66s, http response time is 2304s.
> According to jstack for the thread state, lots of BLOCKED state.
> thread dump log is attached.
> Any hint would be appreciate, thanks!
