Re: Kmail2 display garbled (after a while)
Hi Boris,
I got it again and I guess it has something to do with using Netbeans.
Huhh ? Yes, Netbeans creates many but small shared memory blocks.
I can't find any limit here for the number of shmem blocks nor for a max
memory usage. But somehow it seems limited to 4096 chunks.
I just experienced a garbled Kmail window (when opening a new window for a
reply). I quick check with ipcs in a console says:
$ ipcs -m|grep -c ^0x
4096
I closed Kmail and Netbeans, restarted Kmail and now:
$ ipcs -m|grep -c ^0x
8
I use the original Oracle Netbeans download, Version 8.0.2.
Well, maybe it is not Netbeans but simply Java (OpenJDK 8 here) - I can't say.
However, there seems to be a shmem limit since a few weeks that hasn't been
there before.
Any idea how to proceed ?
