Hi
We are getting consistent memory leaks when writing large amounts of data regardless of the sharing protocol we use (ie same on iSCSI, SMB and NFS). We have a SMB share on 3 x RAIDZ vdevs. Its running at about 40TB used on a 150TB zvol. Dedupe and LZ4 enabled. When the writing is large (ie 1Gbps sustained). RAM is suddenly given up as per the graph below. When that happens the UI becomes unusable and the shares drop
.
and the network traffic dies:
Any ideas? Auto tune isnt set. Have tried it but it makes no difference.
FreeNAS-9.10.1-U2
HP DL360p Gen 9 Chelsio 10Gbp NIC, 2 x Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz, 786GB RAM,
MDS600 SAS disk chasis via a HP H240 HBA with 3 x RAIDZ vdevs consisting of 7 x 8TB 7200rpm SAS drives.
2.4TB stripped L2ARC Intel 3500 NVME SSD
400GB mirrored ZIL Intel 3500 NVME SSD.
