If the IOC with the SEVERITY that does not update meets the following

assessment of the situation. If so, then this is bug 52 in Mantis which, as
Ken mentioned, is fixed in R3.13.10 (and R3.14.5).

o running less than R3.13.10 (or less than R3.14.5) o was at some time in the past very low on network buffers

This problem was probably not identified in the past because, with older
versions of vxWorks, the network buffer pool was expanded when insufficient
to keep up with load. With newer versions of vxWorks the network buffer
pools size is determined when the vxWorks kernel is compiled, and does not
change at runtime.

I have the problem on a vxWorks 5.5 (Tornado 2.2) ioc as well as on a vxWorks 5.3.1 (Tornado 1.0.1). I have changed the network parameters of the 5.5 kernel according to the table in http://www-csr.bessy.de/epics/base/tornado.php (heavy).
