Experimental Physics and Industrial Control System
We use the burt extension heavily for backup and restoration of settings on Linux-based IOCs.
We are seeing the burtrb calls fail when invoked for a large list (~14,000) channels when run on the same LAN as the computer with the IOC. The application successfully completes the ca_search_and_connect calls for all channels, but only gets successful connections for a few hundred channels. Interestingly, the same burtrb call works just fine when run from a computer on a different LAN where an EPICS gateway is used to provide access.
We are using Ubuntu 10.04 (64-bit) with EPICS 3.14.2 on the client.
We tried increasing the number of retries, but all that does is increase the wait time (in 1 second increments) for checking that all connections are made. This does not work.
The Burt extension (as well as the casr extension) have not be updated for 3.14.x. Are there suggestions for an alternate snapshot/restore tool that is being updated?
Thanks
