Explorer often no response

+2 votes
I installed & run explorer following README:

* python -m Mce.abe --config chain1.conf --commit-bytes 100000 --no-serve
* nohup python -m Mce.abe --config chain1.conf &

The explorer run very well. but often no response over a period of time. so I have to kill explorer process and remove sql file and rerun the explorer.

I check the nohup.out and find some error like:

* error: [Errno 104] Connection reset by peer

* error: [Errno 32] Broken pipe

* Exception happened during processing of request from ('', 38796)

I check the node, it's ok for my application, and only explorer no response.

I find some solution in internet, someone suggest to use try ...except to avoid it, but I don't know where can I add the code. I guess this should be done in explorer source code.

I don't know whether there's bugs in explorer or some other reason.

Help me pls.

I check 2750 port : netstat -apn |grep 2750, and found too lots of CLOSE_WAIT, hope useful for the issue.

The most likely explanation is that it is taking the Explorer too long to load a certain page, and that is causing the client requesting the page to give up and close the connection.

Is there some consistent pattern in the types of pages requested from the Explorer that are causing this probkem?
