I somehow doubt it's that the application isn't compatible with a |
| 23 |
newer kernel. If that was the case tell Linus/LKML about it because |
| 24 |
they do a lot to ensure that doesn't happen without really good |
| 25 |
reasons. However don't go that direction until the Cyrus people tell |
| 26 |
you it's the case. |

What follows is just opinion and not something you'd want to depend on... |
| 29 |
|

One possibility is there could be a software API issue down deep |
| 31 |
somewhere not being caught by emerge. I'd personally look at |
| 32 |
rebuilding the app and _all_ of it's libraries, checking app config |
| 33 |
files, etc.. That's usually fixed problems like this for me. |
| 34 |
|
| 35 |
In the couple of cases where I've had this sort of problem happen over |
| 36 |
the years (just a couple) I sort of hate to say my go-to solution is |
| 37 |
to just do an emerge -e @world about once a year. I'll check |
| 38 |
gcc-config, rebuild gcc, then rebuild the whole machine. When all else |
| 39 |
fails that's has fixed this sort of problem for me a couple of times. |
| 40 |
|
| 41 |
I'll also say that if it's really a kernel issue then consider |
| 42 |
bringing up a new kernel with a completely from scratch kernel config |
| 43 |
file. I've seen reports over the years where make oldconfig might have |
| 44 |
caused a problem with a newer kernel. |
| 45 |
|
| 46 |
I know some folks will say is was a waste of time, but I've got time |
| 47 |
for a rebuild (over night on a home server, etc.) but no patience for |
| 48 |
apps failing during the day when I'm trying to work. |
| 49 |
|

Best of luck, |
