After upgrading to 6.7.0 and getting used to for the last couple weeks, decided it was time to upgrade to some larger discs. Started by rebuilding parity with two new 10TB parity drives. Rebuild went OK as anticipated, once finished kicked off a parity check to verify. Got up this morning to check progress and it was going well but noticed speed seemed about half what was expected as the parity check had completed past the point of the slower existing data discs. Took a glance at the syslog and found it to be filled with this repeating:

 

May 29 04:00:44 Tower nginx: 2019/05/29 04:00:44 [crit] 6636#6636: ngx_slab_alloc() failed: no memory May 29 04:00:44 Tower nginx: 2019/05/29 04:00:44 [error] 6636#6636: shpool alloc failed May 29 04:00:44 Tower nginx: 2019/05/29 04:00:44 [error] 6636#6636: nchan: Out of shared memory while allocating message of size 10567.

I let it run awhile to see if errors stop and speed improves, even tried new pause feature, errors seem to have stopped but speed remained the same.

Not sure what is going on or what it means. only thing ive found from some time ago was tied to safari browser but i am using chrome and/or firefox.

Is it connected to disc speed not being what is expected during parity check verify or some other issue to be concerned with??
