OutOfMemoryException in dotConnect for PostgreSQL Professional 7.16.1514
Posted: Thu 21 May 2020 03:45
Hello,
We use PostgreSQL 12.1 and dotConnect for PostgreSQL Professional 7.16.1514.
Our program sometime report following exception and we have to restart when it happen:
Exception occured in Devart.Data.PostgreSql in Void a(Devart.Data.PostgreSql.PgSqlConnection): Exception of type 'System.OutOfMemoryException' was thrown. (stack trace: at Devart.Data.PostgreSql.j.a(PgSqlConnection A_0)

If anybody meet simular issues? Any suggestions for find the reason? Thanks in advance!
