[Serusers] fifo buffer

[Prajyot]

Thanks for your prompt reply,

So if I have to upgrade to the 0.8.14 version, do I have to also change the
database structure or the same database as we have now would work for me. I
am concern since this machine is in production and I want this migration
process to be as transparent as possible.

Regards
Prajyot S

0.8.10 is very very old -- there were a lot of  bugs fixed since that 
release (perhaps many other introduced by the newer releases ;-) ) but 
we do not support anymore 0.8.10. You have to shift to 0.8.14, you will 
get a lot of new feature, no critical bugs which were discover are still 
open, so it is the best option right now.

you have to increase the number of the readers, and I guess in your case 
SER is the writer. Anyhow, in SER is only one process (FIFO server) 
reading from FIFO file.
