Re: [darktable-devel] Fwd: Problem: Exporting takes long time & maxes CPU & RAM after last Linux Mint 13 Software Update

[Mark Heieis]

Hi, I have had the same experience. For me it seems to be related to enabling denoise (profiled). With denoise enabled export takes ~50s or more, without ~4s per image. I think this is to be expected. Although having said that, I've had a few occasions where DT became locked and was consumming 100% of CPU resources (denoise was enabled in these cases but hard to say if denoise was the culprit). Killing its process was required in those cases. As for the lag time, it may also be due to having denoise enabled on most of my images.   On 2014-04-02 11:37, Donal Buckley wrote: Hi all, (First apologies if you've received twice email twice).  I've been using darktable for over a year since about v0.9 and love it. Never had any issues. However since two weeks ago  it has really become unstable or almost unusble when exporting  jpegs. Haven't previously been on the mailing list and joined to report this critical bug.  I'm using darktable 1.4.1.  System is running LinuxMint 13 64-bit (MATE).  Hardware is a Dell e6400 running Intel Core Duo P8400 with 4gb RAM & integrated Intel graphics.  Image Library is on a external 1Gb 7400rpm HDD. There was a LinuxMint Software Manager two weeks ago of various packages and system was updated. No details of what ran in Update manager. Details: Everything seems fine on processing. However when attempting to export an image, the CPU will max (up to 184% in System Monitor) and memory use will increase also, typically around 900 Mb but often higher.  Regardless of number of images selected for processing, from 1 to 16 (all that I've tried) and with image quality set to 90%, unchanged file format of jpeg 8-bit. However the problem manifests regardless of other or no other open applications. The queue will remain open for any extended time. darktable will become laggy, (eg. the lighttable and darkroom views may become mixed or the "working" message may partially display with no exporting queue or no correct format , or the queue may sit there with no apparent processing and the app will have to be closed. Once closed, it will still have to be Ended or Killed via System Monitor or Terminal as it will stay CPU maxed in background. Example: I have been trying to export one single 90%  image with the exporting queue open for 10 minutes with no progress. CPU is showing 178% with Memory varying from 850 to 40 MB. The image is in a folder with one file only. Single Image eventually exported after about 20 minutues. Example 2: Currently trying to export 16 images. Five have processed after 2 hours minutes. RAM is at 1.1gb. CPU varying in System Monitor but CPU applet is constantly showing 100%. Other system functions are sluggish but useable. Hope someone can help, as I currently can process only a limited amount of images over significant period of time.
