Turkish maritime news portal Deniz Haber Ajansı ran a story about the Russian naval exercise scheduled in the Black Sea. According to the news Russian Navy has to cancel at least the amphibious landing part of the exercise due to the fact that Ropucha class landing ships Azov and Yamal were unavailable due to malfunctions. The Turkish portal quotes Ukrainian as their source and I was not able to verify content of the story through other means. But there is no smoke without fire.
Yamal made 3 Syrian deployments in this year and she was last seen on 22th February 2016 sailing north. Whereas Azov made only 2 Syrian deployments in 2016 and she was last seen sailing north on 19th February 2016. So both of them were absent for the last 68 days. This is a long pause suggesting that there actually might be some problems with these ships.
The arduous Syrian Express deployments seems to be taking toll on the auxiliary cargo ships of the Russian Navy as well. According to 7 Feet Beneath the Keel blog half of them are in non-operational status:
“Dvinitsa-50” — operational
“Kazan-60” — non-operational; to undergo repairs – possibly until this fall – following a machinery room fire in late March
“Kyzyl-60” — non-operational
“Vologda-50” — operational
“Aleksandr Tkachenko” — non-operational; after conducting roundtrip missions in February and March, vessel pulled into Feodosiya in mid-March where it probably remains today
“Yauza” — returning to Murmansk

Thanks for posting the article. Maybe the Russians should spend less time making enemies by violating Turkish airspace, invading their neighbors, and trying to intimidate American ships and planes, and more time keeping good relationships with foreign shipyards and engine suppliers.
