Reason for Uncaught Error: Attempting to use a disconnected port object

[marek chovanec]

Hi,

I am getting this error in background page when responding to request
from content script.
Does anyone know what can be causing this error?

Full stack trace:

Uncaught Error: Attempting to use a disconnected port object chrome/
RendererExtensionBindings:147
chrome.Port.postMessage
chrome/RendererExtensionBindings:147
chromeHidden.Port.dispatchOnConnect.connectEvent chrome/
RendererExtensionBindings:89
myExtension.sideSearch.sendResponse.state background.js:1573
db.readTransaction.tx.executeSql.paramStr
background.js:1038

this only happens after a couple of hours of browsing
reloading extension is not helping - not that it would be a solution
after restarting chrome browser all gets back to normal for couple of
hours

content script can keep sending request to background but NO response
from background can be sent back

Is there any way I could catch this Uncaught error and reset the
listener?

I am using chrome.extension.onRequest.addListener for my
communication.

Thanks,
Marek
