Pinned topic Problem CIFS in Nseries
I have a nSeries 6070 serving CIFS and when approximately 1500 users connect simultaneously, it stops giving service CIFS and it is necessary to restart the service.
This failure it has given two times, and coincides with the following informative message:
Message: All CIFS control blocks for the STANDARD pool are in use. The request for a new control block can not be granted.
1500 users connect to the nSeries to execute the Logon Script simultaneously and in addition they create a mapping to a folder lodged at the nSeries
The version of nSeries is 188.8.131.52L1, and each controller has 70 HDD SATA (500Gb).
Which can be the problem?
