Interrupting Study for a Funeral Procession

A person who is studying and hears that there is a funeral, is he obligated to stop and go to accompany the deceased?

He is not obligated to interrupt his study and go to the funeral.

Although in the Gemara in Ketubot (17) and in Shulchan Aruch (Yoreh De'ah, siman 361) it is explained that one must accompany the deceased until there are sixty myriads of escorts for one who has learned and reviewed, and therefore it would seem necessary to interrupt study and go to accompany every Jew who has learned and reviewed. However, there are several leniencies in this matter: A. If he does not know when the actual escorting begins (because during the eulogies it is still not considered a funeral, and there is no obligation to come until they begin to walk after the bier). B. In Even HaEzer, siman 65, Ba'er Hetev, s.k. 3, it is written that if one hears there is a funeral, even if he does not see it, he is obligated to accompany, but in Haamek She'ela, Sheilta 14, letter b and 34, letter b, it is proven that only if he sees the funeral is he obligated to interrupt and accompany, but if he hears, there is no obligation. C. In Tosafot in Ketubot 17, d.h. 'Mevatlin', it is written in the name of the Ri of Corbeil that all that they interrupt Torah study for the funeral is only when studying Torah, but if serving a Torah scholar, which is 'greater than learning', they do not interrupt for the funeral. And studying Gemara in depth is considered serving a Torah scholar (see Berachot 47 and Rashi there, Rashi in Sotah 22, Bava Metzia 33, Bava Batra 145, and see Or Sameach, p.1 from Talmud Torah).
