We are running FreeBSD 10.1 and we had 4 1 TB SSDs in L2ARC which we removed and made into a separate zpool. I ran sysctl and noticed a strange message showing this lost memory. I have pasted output of sysctl -a |grep UMA. Any idea why this is happening ? Any fixes or suggested solution ? hosts (1/10): sjc1-prod1-01.voxer.com Freed UMA keg (zio_data_buf_1024) was not empty (333 items). Lost 171 pages of memory.
