We're both linux admins on a team of two. We were both recently assigned to a new group of systems we have very little experience with. A developer raised an issue with a plugin on one of the sites they were using and said it wasn't working. Boss assigned it to the coworker.
It's been three months and he's opened tickets with the vendor, troubleshot it himself, did screen shares with the developers and was unable to solve it.
The developer pinged me today and I had some time, so I looked into it. It took me about 2 hours to find the problem and another 2 hours to implement a solution. I update ticket with resolution notes and close it out.
My coworker messages me and asks if it was that simple, why didn't I help him, ect. and seems to be implying that I have been watching him struggle for 3 months while having the solution. While I was aware that he was working on it, I never had the time to ever bother looking into it until today. He is supposed to be very experienced, so I assumed it was just some sort of complex problem if it took him that long to figure it out. I am not sure what to tell him or how to deal with him at this point.
