zcom 00235: Card <#> - I/O suspended due to lack of ZCOM buffers.
Explanation: When the ACC card indicates an inbound data buffer
needs to be transferred to the host, the driver attempts
to allocate a buffer to DMA the data into. This message
is logged when there are no free buffers remaining in
the ZCOM buffer pool. The driver has disabled the card
from interrupting it for inbound data requests until
there is sufficient free space available in the buffer
pool.
Action: This is usually due to an improperly coded application
which uses the ZCOM API. Most likely, an application
is failing to read inbound data from its program ZLU.
This could also occur if the application terminates with
out cleaning up its program ZLUs and removing any
receivers it has setup. In rare cases, it could be due to a
Buffer-Pool parameter value that is too small.
zcom 00236: Card <#> - ZCOM buffers now available, I/O resumed.
Explanation: This message is logged when the driver has had to
suspend inbound data processing due to a lack free
space (buffers) in the ZCOM buffer pool and the driver
now detects that sufficient free space is available to
continue processing inbound data.
Action: This is an informational message.
