Compression stalls, does not recover, and compression facilities may cease.
In general, compression stops altogether. Under some circumstances, compression requests may end up routed to zlib (software compression), but generally the SSL hardware accelerator card does not correctly report that it is unavailable when it stalls.
A device error of any kind, or requests that result in the device reporting an error (for example, attempting to decompress an invalid compression stream).
Select the softwareonly compression provider by running the following tmsh command: tmsh modify sys db compression.strategy value softwareonly.
The compression device driver now attempts to recover after a failure. If it still cannot recover, new compression requests will be assigned to zlib (software) for compression.
