Couch db throwing error "Error: normal. Reason: {gen_server,call,[<0.24064.2493>, {pread_iolist,327789}"

[rummitta]

Hi Team, We are using Couch db v 3.2.2. While trying to access a db view through automation, we are getting the below error Error: normal. Reason: {gen_server,call,[<0.24064.2493>, {pread_iolist,327789} The actual error looks like this: Error at http://host:5984/execonfig/_design/execonfig/_view/by_applicationName?key=%5B%22INU_UI%22,%22POC%22%5D. Error: normal. Reason: {gen_server,call,[<0.24064.2493>, {pread_iolist,327789} ,infinity]}. However, if we try to access that url separately from browser, we are able to get response. Please let us know what is the cause of this error and how to avoid this. Regards, Rumki

Hi, can you append your log file?

hi, we are not getting the error now. The earlier couch db pod log seems to have rolled over. We will monitor this issue and get back in case it occurs again.

Hi, I don't know if it helps, I often get the same error. In the Couch logs, there are some more details, but I have no experience with CouchDB's internals so I don't really know what it means...

I get the error sometimes when querying a view, but it seems to happen randomly.

I'm using CouchDB 3.3.3.
