Re: [Virtuoso-users] Virtuoso 7 query intermittently failing to return results

Actually, the explain plan was from a pattern in an earlier testcase that also failed. The one listed has this explain plan. REPORT VARCHAR { RDF_QUAD_POGS 8 rows(s_10_2_t0.S) P = ##type , O = #/APIConsumer G = #/Precode: 0: S := Call __id2in (s_10_2_t0.S) 5: BReturn 0 RDF_QUAD_GS unq 0.

[Virtuoso-users] Virtuoso 7 query intermittently failing to return results

This appears to be an intermittent error that pops up every few weeks, restarting the DB usually resolves it though not this time. The query that fails is of the form: sparql prefix o: select * from { ?S a o:myClass . #?S ?P ?O . } It works until I re

Re: [Virtuoso-users] queries and CPU

Hi Roland, Did you try changing the ThreadsPerQuery setting in your virtuoso.ini file to the number of cpu's in your machine? That seems to help in my case. Although some queries remain IO bound on my desktop machine and I don't always get 100% cpu usage. Regards, Jerven On 19/02/14 17:46, Ro
