If a stop-the-world GC is in progress, it is not possible for an external service to know if this is because a GC is in progress or the node is dead. If the GC takes longer than the relevant timeouts, the external conclusion is that it is dead. In you next post you state that there is very heavy GC going on, so it would seem that your main problem is that your heap is too small for your setup. Getting OOM for a 200GB index with 24GB heap is not at all impossible, but it is a bit of a red flag. If you have very high values for your caches or perform faceting on a lot of different fields, that might be the cause. If you describe your setup in more detail, we might be able to help find the cause for your relatively high heap requirement. - Toke Eskildsen, State and University Library, Denmark
