It looks to me like the switch is closing the connection, not the
controller. So this is probably a question for HP ... ?
Hello
I am running on a topology of 9 switches. It uses both HP switch and
NEC switch. What is the meaning of the following error? Is it the
controller connection breaking out?
When this occurs, I remember the number of entries is less than 1500,
actually around 800 for HP. What are the possible reasons forcing HP
switches to leave? The CPU of controller? Is there any limit on the
number of entries per virtual switch (per vlan)?

such process.
=====================================================
On the NEC switch, it also occasionally shows error type 3 code 0,
meaning the flow table is full, but it seems to me not full, around
1000 or less. Is there a limit on the number of entries per virtual
switch (not physical switch)?
Thanks.
