Postgres transaction error

Hi,

I am using postgres database in my application. Today I have saw in
application's log the following error

ERROR: current transaction is aborted, commands ignored until end of
transaction block

After this exception all the users lose access to the application.
If the problem has been generated by a error in my application, I think this
error only must affect the current transaction but no other transactions.
I am not sure what is the cause of this problem, can you help me?

This is exception's stack trace:
