SecuritySpy has a large memory buffer of data that is used to buffer writes to the drive and smooth out temporary drive slow-downs, but when this gets full because the drive can't keep up with the amount of data that is being attempted to be written to it, there is nothing SecuritySpy can do but to stop recording and throw this error. This message does indicate a real problem. The odd thing is it is the same frame# and will list all the different cameras in the 'xx' section.Īny thoughts on this? Would it be helpful to send over any files/logs? The disk is too slow and cannot keep up with writing data - you may meed to reformat or replace the disk. My hardware/network has not changed in the last 3+ years bar the router/firewall about a year ago.Įrror performing continuous capture for the camera "xx" continuous capture mode has been disarmed. I have run SS for the last 6 or so years on the same core hardware, upgrading components and OS over time. This issue only started about 3-4months ago. The Xserve is running 10.11.6 with Svr5.1.7 and has been for a couple of years now (10.9 for a few years prior to that then 10.6 prior to that). Everything is CAT6 gig linked (some cameras are only 100Mb though) all routed through a Cisco 3750G-48. There are 2 x Quad Core Xeon CPU's humming along with about 80% idle for the most. The System Drive is a 6Gb SAS SSD with 60% Free, and 24GB RAM with plenty free.
There is about 6% free space on the Array (as managed by SecuritySpy). Manually copying files onto the array and back is very fast. All drives 'smart' report ok, array integrity is 100% and all other services on the server are working normally. This was over many tests using BlackMagicDesign Disk Speed Test. The thing is, the hardware hasn't changed and running a speedtest on the 6Gb SAS 12TB formatted RAID6 array (at the same time as the 5 cameras are recording to it) I am getting a consistent throughput of 570MB write and 630MB read. Sometimes nothing for a few days, other times, non stop for a day.
I get the error window up and a massive list of these pouring in (in batches). In the last couple of releases of the software, I have started to get a glitch occur.
