Re: [Bigdata-developers] After a timeout I get only timeouts

[Daniel H. <da...@de...>]

Michael, I set swap off as you suggest.

Then, I started the process with:

java -Xmx6g -XX:+UseG1GC -Dbigdata.propertyFile=server.properties -jar 
blazegraph.jar

Then, I check jstat -gcutil.

Before receiving queries:

   S0     S1     E      O      P     YGC     YGCT    FGC    FGCT     GCT
   0.00 100.00   5.74  26.17  92.52     24    0.477     0    0.000    0.477

While receiving queries before the timeout:

   S0     S1     E      O      P     YGC     YGCT    FGC    FGCT     GCT
   0.00 100.00  46.00  76.97  99.26     13    0.269     0    0.000    0.269

After the first timeout:

   S0     S1     E      O      P     YGC     YGCT    FGC    FGCT     GCT
   0.00 100.00  22.67  85.96  96.57    248    2.289     0    0.000    2.289

I notice that values YGC, YGCT and GCT increases a lot. In this 
experiment it occurs at query 106. I shuffle the queries every time, so 
is not problem of queries, is something that occurs after some queries 
are executed.

Cheers,
Daniel
