segfault runninng fio against 2048 jobs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Everyone,

I am using a 2.0x variant ran across a couple of things, one of which looks to be as designed and the other was a segfault in fio.

My original job file had 4800 entries which exceeds the max limit. (error: maximum number of jobs (2048) reached)  The question I have here , is there a reason the limit can't be raised to handle larger job files?

Reducing the job file to the max re-running it jumped straight to the initial print screen and then to a segfault. (Segmentation fault (core dumped))

Doing a quick look gave me

I reduced the job count down to about 33 and re-started the run which I am waiting to finish so I can re-compile fio with whatever extra flags and to whatever code level are requested.  Currently file gives me:

Thanks,
Roger
