Hi Vikram,
You should implement a caching and not update the table that frequently.
The agent cannot respond to requests while the updating thread is in the
synchronized {...} block.If you have purchased SNMP4J-AgentX you could also use the BufferedMOTableModel which is available in the latest SNMP4J-AgentX snapshot release (version 2.2 will be released within the next 14 days). Best regards, Frank Am 15.03.2014 16:55, schrieb VIKRAM MODUGU:
Hi Frank, When we have put heavy load on on snmp agent, it seems the agent is becoming unresponsive for some time tentatively. There is other scenario, where are getting the time out from the snmp agent. Can you pls give me the scenarios where all the possibilities of getting snmp time out message when we do the snmp walk? did you find fault in our implementation of updating the table model. Thanks, Vikram. ________________________________________ From: [email protected] [[email protected]] on behalf of [email protected] [[email protected]] Sent: Saturday, March 15, 2014 4:30 PM To: [email protected] Subject: SNMP4J Digest, Vol 86, Issue 11 Send SNMP4J mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit https://s16675406.onlinehome-server.info/mailman/listinfo/snmp4j or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of SNMP4J digest..."

We have a scenario of having 50k records in a particular mib table, here we are giving how we are loading the content into the motable model. MOMutableTableModel model = (MOMutableTableModel) table.getModel(); synchronized (model) { model.clear(); Map<Integer, String> domainMap = postgresServ.getAllAvailableDomains(); logger.info("Acquired the lock on associated clients table model."); List<AssociatedClient> assocClientList = redisServ .getAssociatedClientsInfo(); int recCount = 1; for (AssociatedClient client : assocClientList) { model.addRow(new DefaultMOMutableRow2PC(),Variable[]); } } This table content is very dynamic in nature, they change very frequently. Can you pls clarify us if there is something wrong we are doing? We are using snmp4j agent version 2.1.0 and snmp4j api version 2.0.2.

Is an exception being thrown? Does the agent hang (i.e. not responding anymore)?
